The level of the water in the reservoir is 50 ft above the pump discharge, and the average speed of the water in the pipe is 10 ft/s. Calculate the pressure at the pump discharge.

Water (density = 62.4 lb/ft³, viscosity = 1 cP) is pumped from a large
reservoir on the floor at a rate of 80 gpm to the top of a smaller tower.
The discharge point is 20 ft above the centerline of the pump.
Frictional and other (contraction, expansion, etc.) losses in suction and
discharge lines amount to 1.5 ft head of liquid. If the pump develops
only 1/4 hp, the water height (ft) in the reservoir must be closest to

Water from a reservoir is pumped over a hill through a pipe 3 ft. in diameter, and a pressure of 35 psi is maintained at the summit, where the pipe is 300 ft above the reservoir. The quantity pumped is 55 cfs, and by reason of friction in the pump pipe there is 10 ft of head loss between the reservoir and the summit. What amount of energy must be furnished the water by the pump in kilowatts?
A pump is required to transfer water at the rate of 350 kg/s from an open sump to an open storage tank located 30m above the pump. The sucLon pipe is 350mm in diameter and 12m in length and the delivery pipe is 550mm in diameter and 40m in length. Calculate:(a) The maximum height at which the pump may be placed above the sump, so that pressure at the inlet is not less than -80 kPa (gauge) (b) the energy to be supplied by the pump per unit mass of water transferred (c) The input power required by the pump, which is 60 % efficient
