The head-discharge relationship for a certain pump can be represented by the equation H = 28 -9Q². The pump is fixed 2.5 m above the water surface in a river and it forces the water to a tank at a level 10 m above the pump. The suction and delivery pipes are 15 m and 740 m long, respectively and each pipe is 0.5 m in diameter. The pipe coefficient of friction (f) is 0.017. Estimate the discharge (in m³/s) at the best operating point for the pumping system. Q = 0.6 m³/s Q = 0.9 m³/s Q = 0.4 m³/s Q = 1.1 m³/s

QUESTION SIX (6a) A siphon is made of a pipe whose inside diameter is 25.4 mm and is used to maintain a constant level in a 6.0975m deep tank (Fig. 6.1). If the siphon discharge is 9.144m below the top of tank, what will be the flow rate if the fluid level is 1.524m below the top of tank? Z₁ = 6.0975 m 1.524 m U tube Fig. 6.1 (6b) Briefly explain any five components of water cycle N Z₁ = 9.144 m

Given the following data for three pipes in parallel: Pipe 1: D1 = 450 mm, L1 = 800 m ; Pipe 2: D2 = 400 mm, L2 = 700 m; Pipe 3: D3 = 500 mm, L3 = 600 m. The total flow is 0.86 m3/s. Assume f = 0.02 for all pipes Determine the flow in pipe 1 in m3/s Determine the flow in pipe 2 in m3/s Determine the flow in pipe 3 in m3/s
