35. (a) A reservoir A discharges water to a lower reservoir B through a 3600 m long pipe of diameter 600 mm. The flow is due to gravity and the difference in surface water levels in A and B is 13 m. Reservoir A is now required to supply water also to a third reservoir C, the water surface of which is 15 m below that of A. The discharge to C is to be made from a 1200 m...
Q3 (40 pts): Water is pumped through a 60-m-long, 0.3-m-diameter pipe from a lower reservoir to a higher reservoir, which has a water surface 10 m above the lower one. When the pump adds 40 kW to the water the flowrate is 0.20 m/s. Assume the following coefficients of minor losses: • Entrance: Kentrance = 0.5 Exit: Kexit = 1 Each elbow: Kelbow = 1.5 • Valve: K= 6 Part A (20 pts) Determine the pipe roughness ε. Part B...
Problem 4 (50 points) water is discharged from a reservoir at a rate of 18.103 m2/s using two horizontal cast iron pipes nected in series and a pump between them. The first pipe is 20 m long and has a 6-cm diameter, while the second pipe is 35 m long and has a 4-cm diameter. The water level in the reservoir is 30 m above the centerline of the pipe. The pipe entrance is sharp-edged. Losses associated with the connection...
A reservoir A connected to B reservoir through a pipe that is 5 km long and 230 mm in diameter. The difference in water level of the two reservoirs is 70 m. At a distance of 2 km from the feeder reservoir, water is drawn at the rate of 40 litres/s . (a) Taking the friction factor as 0.008 and neglecting all other losses, determine the rate at which water enters the B reservoir. (b) Sketch the hydraulic grade line...
