Example 6.5. The lowest level of an impounding reservoir, situated in hills and being used as a source of supply, is higher than the lepel of the service reservoir by 150 metres and the distance between them is 50 km. The storgge Teormoir and the service reservoir were originally connected by a single pipe line designed to carry a max. daily. demand' of 24 million litres per day. However, it was later found necessary to increase the supply to 35 million litres ner day. It was, therefore, decided to lay another pipe of the same diameter alongside the first one in a certain reqd. length and cross-connected. Calculate the dia. of the pipes and the length of second pipe required to be laid. Make use of William Hazen's equation. Also derive an expression expressing H, in terms of L and d from the original William Hazen's formula. Assume C7 = 120. %3D

Please include a free body diagram A new 45 cm CI pipe, 600 m long carries 260 L/s of water from an upper reservoir A, and flows into two new cast-iron pipes each 500 m long connected to two lower reservoirs. One pipe is 30 cm in diameter that leads to reservoir B, with water surface 5.0 lpwer than that in A. If the water surface in the third reservoir C is 2.0 m lpwer than that in B, what is the size of the pipe leading to C. Use Manning's n= 0.011.Neglect minor losses.
