Old Urdu dictionaries also contain most of the Sanskrit words now present in Hindi. Mutual intelligibility decreases in literary and specialised contexts that rely on academic or technical vocabulary. In a longer conversation, differences in formal vocabulary and pronunciation of some Urdu phonemes are noticeable, though many native Hindi speakers also pronounce these phonemes. At

This project effectively raised the dam height by 30 feet to 482 feet (147 m), thereby raising the maximum water conservation level from 1202 feet to 1242 feet. This increased the dam's storage capacity from 5.56 to 9.12 billion m (4.51 to 7.39 million acre⋅ft). Besides, it is expected that after raising the height of the Mangla Dam by 30 feet,
660-546: A heavy influence on both as a co-official language. According to Bruce (2021), Urdu has adapted English words since the eighteenth century. A movement towards the hyper-Persianisation of an Urdu emerged in Pakistan since its independence in 1947 which is "as artificial as" the hyper-Sanskritised Hindi that has emerged in India; hyper-Persianisation of Urdu was prompted in part by the increasing Sanskritisation of Hindi. However,

Urdu speakers will often insert vowels to break up consonant clusters found in words of Sanskritic origin, but will pronounce them correctly in Arabic and Persian loanwords. As a result of religious nationalism since the partition of British India and continued communal tensions, native speakers of both Hindi and Urdu frequently assert that they are distinct languages. The grammar of Hindi and Urdu

Urdu had been used as a literary medium for British colonial Indian writers from
1540-481: A significant role in the development of the Urdu register. Hindi became the distinct register spoken by those who sought to construct a Hindu identity in the face of colonial rule. As Hindi separated from Hindustani to create a distinct spiritual identity, Urdu was employed to create a definitive Islamic identity for the Muslim population in India. Urdu's use was not confined only to northern India – it had been used as
1650-614: A symbol of their religious identity. Hindus in northwestern India, under the Arya Samaj agitated against the sole use of the Perso-Arabic script and argued that the language should be written in the native Devanagari script, which triggered a backlash against the use of Hindi written in Devanagari by the Anjuman-e-Islamia of Lahore. Hindi in the Devanagari script and Urdu written in the Perso-Arabic script established
1760-419: A uniting language. Urdu was chosen as a symbol of unity for the new Dominion of Pakistan in 1947, because it had already served as a lingua franca among Muslims in north and northwest of British Indian Empire . Urdu is also seen as a repertory for the cultural and social heritage of Pakistan. While Urdu and Islam together played important roles in developing the national identity of Pakistan, disputes in

#17327650126802420-404: Is a type of reaction turbine, a category of turbine in which the working fluid comes to the turbine under immense pressure and the energy is extracted by the turbine blades from the working fluid. A part of the energy is given up by the fluid because of pressure changes occurring on the blades of the turbine, quantified by the expression of degree of reaction , while the remaining part of the energy
2530-476: Is equal to that at the inlet to the draft tube. Using the Euler turbine equation, E / m = e = V w1 U 1 , where e is the energy transfer to the rotor per unit mass of the fluid. From the inlet velocity triangle, and Therefore The loss of kinetic energy per unit mass at the outlet is V f2 /2 . Therefore, neglecting friction, the blade efficiency becomes i.e. Degree of reaction can be defined as
2640-445: Is extracted by the volute casing of the turbine. At the exit, water acts on the spinning cup-shaped runner features, leaving at low velocity and low swirl with very little kinetic or potential energy left. The turbine's exit tube is shaped to help decelerate the water flow and recover the pressure. Usually the flow velocity (velocity perpendicular to the tangential direction) remains constant throughout, i.e. V f1 = V f2 and

Draft tube : The draft tube is a conduit that connects the runner exit to the tail race where the water is discharged from the turbine. Its primary function is to reduce the velocity of discharged water to minimize the loss of kinetic energy at the outlet. This permits the turbine to be set above the tail water without appreciable drop of available head. The Francis turbine
2970-527: Is not officially recognised by the Government of Bangladesh . The Urdu spoken by Stranded Pakistanis in Bangladesh is different from this dialect. Many bilingual or multi-lingual Urdu speakers, being familiar with both Urdu and English, display code-switching (referred to as " Urdish ") in certain localities and between certain social groups. On 14 August 2015, the Government of Pakistan launched

8250-811: The irrigation system of the country as part of the Indus Basin Project , with the other being the Tarbela Dam situated on the Indus River in Swabi , Khyber Pakhtunkhwa . The Mangla Dam was constructed at a cost of ₨ 1,558.7 billion ( US$ 14.73 billion) with funding being provided by the World Bank and the Asian Development Bank . The dam was constructed between 1961 and 1965 across the Jhelum River and Poonch River in
8360-554: The language as " Moors " or "Moorish jargon". John Gilchrist was the first in British India to begin a systematic study on Urdu and began to use the term "Hindustani" what the majority of Europeans called "Moors", authoring the book The Strangers's East Indian Guide to the Hindoostanee or Grand Popular Language of India (improperly Called Moors) . Urdu was then promoted in colonial India by British policies to counter
8470-458: The language in the Perso-Arabic script in courts and government offices, though Hindus continued to employ the Devanagari script in certain literary and religious contexts. Through the late 19th century, people did not view Urdu and Hindi as being two distinct languages, though in urban areas, the standardised Hindustani language was increasingly being referred to as Urdu and written in the Perso-Arabic script. Urdu and English replaced Persian as
8580-575: The language of Bollywood films tend to contain a large number of Persian and Arabic words and thus considered to be "Urdu" in a sense, especially in songs. India has more than 3,000 Urdu publications, including 405 daily Urdu newspapers. Newspapers such as Neshat News Urdu , Sahara Urdu , Daily Salar , Hindustan Express , Daily Pasban , Siasat Daily , The Munsif Daily and Inqilab are published and distributed in Bangalore, Malegaon, Mysore, Hyderabad, and Mumbai . Outside South Asia, it
8690-883: The language. In India, Urdu is spoken in places where there are large Muslim minorities or cities that were bases for Muslim empires in the past. These include parts of Uttar Pradesh , Madhya Pradesh , Bihar , Telangana , Andhra Pradesh , Maharashtra ( Marathwada and Konkanis), Karnataka and cities such as Hyderabad , Lucknow , Delhi , Malerkotla , Bareilly , Meerut , Saharanpur , Muzaffarnagar , Roorkee , Deoband , Moradabad , Azamgarh , Bijnor , Najibabad , Rampur , Aligarh , Allahabad , Gorakhpur , Agra , Firozabad , Kanpur , Badaun , Bhopal , Hyderabad , Aurangabad , Bangalore , Kolkata , Mysore , Patna , Darbhanga , Gaya , Madhubani , Samastipur , Siwan , Saharsa , Supaul , Muzaffarpur , Nalanda , Munger , Bhagalpur , Araria , Gulbarga , Parbhani , Nanded , Malegaon , Bidar , Ajmer , and Ahmedabad . In
8800-759: The leadership of the Muslim League in Pakistan and the Hindu-dominated Congress Party in India had been educated in English during the British colonial period, and continued to operate in English and send their children to English-medium schools as they continued dominate both countries' post-Partition politics. Although the Anglicized elite in Pakistan has made attempts at Urduisation of education with varying degrees of success, no successful attempts were ever made to Urduise politics,
8910-466: The legal system, the army, or the economy, all of which remained solidly Anglophone. Even the regime of general Zia-ul-Haq (1977–1988), who came from a middle-class Punjabi family and initially fervently supported a rapid and complete Urduisation of Pakistani society (earning him the honorary title of the 'Patron of Urdu' in 1981), failed to make significant achievements, and by 1987 had abandoned most of his efforts in favour of pro-English policies. Since
9020-585: The length is 6,800 ft (2,100 m). The main spillway is a submerged orifice type with 9 radial gates, 36 ft (11 m) x 40 ft (12 m) each; it has a maximum capacity of 1.1 million cusecs. The emergency spillway is a weir type with an erodible bund and a maximum capacity of 0.23 million cusecs. The 5 tunnels are steel and concrete lined and 1,560 feet long in bedrock. The internal diameter ranges between 26 ft (7.9 m) and 31 ft (9.4 m). The powerhouse, which consists of turbines, generators, and transformers, has been constructed at
9130-404: The main languages of instruction, although the people from differing provinces may have different native languages. Urdu is taught as a compulsory subject up to higher secondary school in both English and Urdu medium school systems, which has produced millions of second-language Urdu speakers among people whose native language is one of the other languages of Pakistan – which in turn has led to
9240-457: The majority population in the city of Karachi , however. Many newspapers are published in Urdu in Pakistan, including the Daily Jang , Nawa-i-Waqt , and Millat . No region in Pakistan uses Urdu as its mother tongue, though it is spoken as the first language of Muslim migrants (known as Muhajirs ) in Pakistan who left India after independence in 1947. Other communities, most notably
9350-403: The most Urdu-speaking states of Uttar Pradesh (c. 8% to 5%) and Bihar (c. 11.5% to 8.5%), even though the number of Muslims in these two states grew in the same period. Although Urdu is still very prominent in early 21st-century Indian pop culture, ranging from Bollywood to social media, knowledge of the Urdu script and the publication of books in Urdu have steadily declined, while policies of
9460-564: The most alive language and moving ahead with times" in India. This phenomenon pertains to the decrease in relative and absolute numbers of native Urdu speakers as opposed to speakers of other languages; declining (advanced) knowledge of Urdu's Perso-Arabic script, Urdu vocabulary and grammar; the role of translation and transliteration of literature from and into Urdu; the shifting cultural image of Urdu and socio-economic status associated with Urdu speakers (which negatively impacts especially their employment opportunities in both countries),
9570-461: The official languages in northern parts of India in 1837. In colonial Indian Islamic schools, Muslims were taught Persian and Arabic as the languages of Indo-Islamic civilisation ; the British, in order to promote literacy among Indian Muslims and attract them to attend government schools, started to teach Urdu written in the Perso-Arabic script in these governmental educational institutions and after this time, Urdu began to be seen by Indian Muslims as
9680-578: The officially recognised languages in India and also has the status of "additional official language" in the Indian states of Andhra Pradesh , Uttar Pradesh , Bihar , Jharkhand , West Bengal , Telangana and the national capital territory Delhi . Also as one of the five official languages of Jammu and Kashmir . India established the governmental Bureau for the Promotion of Urdu in 1969, although
9790-438: The ongoing Hindi–Urdu controversy and modern cultural association of each language with the two religions has led to fewer Hindus using Urdu. In the 20th century, Indian Muslims gradually began to collectively embrace Urdu (for example, 'post-independence Muslim politics of Bihar saw a mobilisation around the Urdu language as tool of empowerment for minorities especially coming from weaker socio-economic backgrounds' ), but in
9900-607: The outside of the turbine's rotating runner controls the rate of water flow through the turbine for different power production rates. Francis turbines are usually mounted with a vertical shaft, to isolate water from the generator. This also facilitates installation and maintenance. Water wheels of different types have been used for more than 1,000 years to power mills of all types, but they were relatively inefficient. Nineteenth-century efficiency improvements of water turbines allowed them to replace nearly all water wheel applications and compete with steam engines wherever water power
10010-454: The position and prestige of English only grew stronger in the meantime. There are over 100 million native speakers of Urdu in India and Pakistan together: there were 50.8 million Urdu speakers in India (4.34% of the total population) as per the 2011 census; and approximately 16 million in Pakistan in 2006. There are several hundred thousand in the United Kingdom, Saudi Arabia, United States, and Bangladesh . However, Hindustani, of which Urdu
10120-480: The power house will generate 12 percent additional energy per year which will increase its installed capacity from 1,000 MW to 1,120 MW. The Mangla Dam Raising Project, however, has affected more than 40,000 people living in the vicinity of the dam. The total cost of compensation and resettlement was Rs. 70 billion. The resettlement project includes the construction of New Mirpur City , four satellite towns (Islamgarh, Chakswari, Dadyal, Siakh) with all civic amenities,
10230-488: The powerhouse. Each of these turbines has an output of 138,00 bhp with a rated head of 295 feet of water. The first four turbines were manufactured by Mitsubishi Electric , Japan and were installed in 1969, turbines 5 and 6 are manufactured by ČKD Blansko , the Czech Republic and were installed in 1974, turbines 7-8 were manufactured by ACEC , Belgium and were installed in 1981, while the remaining two turbines are
10340-484: The previous emphasis on Persian. In colonial India, "ordinary Muslims and Hindus alike spoke the same language in the United Provinces in the nineteenth century, namely Hindustani, whether called by that name or whether called Hindi, Urdu, or one of the regional dialects such as Braj or Awadhi ." Elites from Muslim communities, as well as a minority of Hindu elites, such as Munshis of Hindu origin, wrote
10450-433: The ratio of pressure energy change in the blades to total energy change of the fluid. This means that it is a ratio indicating the fraction of total change in fluid pressure energy occurring in the blades of the turbine. The rest of the changes occur in the stator blades of the turbines and the volute casing as it has a varying cross-sectional area. For example, if the degree of reaction is given as 50%, that means that half of
10560-400: The runner. These openings convert the pressure energy of the fluid into kinetic energy just before the fluid impinges on the blades. This maintains a constant velocity despite the fact that numerous openings have been provided for the fluid to enter the blades, as the cross-sectional area of this casing decreases uniformly along the circumference. Guide and stay vanes : The primary function of
10670-646: The same language, Hindustani (or Hindi-Urdu), share a core vocabulary and grammar . Apart from religious associations, the differences are largely restricted to the standard forms : Standard Urdu is conventionally written in the Nastaliq style of the Persian alphabet and relies heavily on Persian and Arabic as a source for technical and literary vocabulary, whereas Standard Hindi is conventionally written in Devanāgarī and draws on Sanskrit . However, both share
10780-606: The same principles. S. B. Howd obtained a US patent in 1838 for a similar design. In 1848 James B. Francis , while working as head engineer of the Locks and Canals company in the water wheel-powered textile factory city of Lowell, Massachusetts , improved on these designs to create more efficient turbines. He applied scientific principles and testing methods to produce a very efficient turbine design. More importantly, his mathematical and graphical calculation methods improved turbine design and engineering. His analytical methods allowed
10890-583: The style of Urdu spoken on a day-to-day basis in Pakistan is akin to neutral Hindustani that serves as the lingua franca of the northern Indian subcontinent. Since at least 1977, some commentators such as journalist Khushwant Singh have characterised Urdu as a "dying language", though others, such as Indian poet and writer Gulzar (who is popular in both countries and both language communities, but writes only in Urdu (script) and has difficulties reading Devanagari, so he lets others 'transcribe' his work) have disagreed with this assessment and state that Urdu "is
11000-565: The toe of an intake embankment at the ground surface elevation of 865 feet SPD. The water to the powerhouse is supplied through five steel-lined tunnels of 30/26 feet diameter. Each tunnel is designed to feed two generating units. The powerhouse tailrace discharges into New Bong Canal, which has a length of 25,000 feet with a discharge capacity of about 49,000 cusecs, and terminates at an automatic gate control headworks at about 12 km downstream located near old Bong Escape Headworks. There are ten vertical Francis type turbines in
11110-883: The total energy change of the fluid is taking place in the rotor blades and the other half is occurring in the stator blades. If the degree of reaction is zero it means that the energy changes due to the rotor blades is zero, leading to a different turbine design called the Pelton Turbine . The second equality above holds, since discharge is radial in a Francis turbine. Now, putting in the value of 'e' from above and using V 1 2 − V f 2 2 = V f 1 2 cot α 2 {\displaystyle V_{1}^{2}-V_{f2}^{2}=V_{f1}^{2}\cot \alpha _{2}} (as V f 2 = V f 1 {\displaystyle V_{f2}=V_{f1}} ) Francis turbines may be designed for
11220-618: The two languages' mutual intelligibility effectively decreases as the factor of formality increases. Urdu originated in the area of the Ganges-Yamuna Doab , though significant development occurred in the Deccan Plateau . In 1837, Urdu became an official language of the British East India Company , replacing Persian across northern India during Company rule ; Persian had until this point served as
11330-425: The two official languages of Pakistan (along with English). It is spoken and understood throughout the country, whereas the state-by-state languages (languages spoken throughout various regions) are the provincial languages , although only 7.57% of Pakistanis speak Urdu as their first language. Its official status has meant that Urdu is understood and spoken widely throughout Pakistan as a second or third language. It
11440-550: The waters of the Ravi , Sutlej and Beas rivers, while Pakistan , in addition to the waters of the aforementioned three rivers' sections within Pakistani territory and some monetary compensation, received the rights to develop the Jhelum , Chenab and Indus river basins. Until 1967, the entire irrigation system of Pakistan was fully dependent on unregulated flows of the Indus River and its major tributaries . The agricultural yield
11550-455: The world , with 230 million total speakers, including those who speak it as a second language . The name Urdu was first used by the poet Ghulam Hamadani Mushafi around 1780 for Hindustani language even though he himself also used Hindavi term in his poetry to define the language. Ordu means army in the Turkic languages . In late 18th century, it was known as Zaban-e-Urdu-e-Mualla زبانِ اُرْدُوئے مُعَلّٰی means language of
11660-402: Was 4797.425 Million KWh while the station shared a peak load of 1150 MW which was 8.18% of the total WAPDA system peak. On 1 September 2013, the water level in Mangla Dam reached a record height of 1237.15 feet against the maximum conservation level of 1242 feet. Radio Pakistan reported that "the water level in Mangla Dam has attained the maximum height of 1237.15 feet in the history and it
11770-520: Was available. After electric generators were developed in the late 1800s, turbines were a natural source of generator power where potential hydropower sources existed. In 1826 the French engineer Benoit Fourneyron developed a high-efficiency (80%) outward-flow water turbine. Water was directed tangentially through the turbine runner, causing it to spin. Another French engineer, Jean-Victor Poncelet , designed an inward-flow turbine in about 1820 that used
11880-611: Was intentioned as means of unification for Muslims in Northern India and later Pakistan, it adopted a modified Perso-Arabic script. Urdu continued its role in developing a Pakistani identity as the Islamic Republic of Pakistan was established with the intent to construct a homeland for the Muslims of Colonial India. Several languages and dialects spoken throughout the regions of Pakistan produced an imminent need for
11990-555: Was referred to as "Moors", which simply meant Muslim, by European writers. John Ovington wrote in 1689: The language of the Moors is different from that of the ancient original inhabitants of India but is obliged to these Gentiles for its characters. For though the Moors dialect is peculiar to themselves, yet it is destitute of Letters to express it; and therefore, in all their Writings in their Mother Tongue, they borrow their letters from
12100-426: Was very low for a number of reasons, the most significant being a lack of water during critical growing periods. This problem stemmed from the seasonal variations in river flow due to monsoons and the absence of storage reservoirs to conserve the vast amounts of surplus water during those periods of high river discharge. The Mangla Dam was the first of the two dams constructed to reduce this shortcoming and strengthen
