Give me right solution according to the question..
Compute the power required to operate and the efficiency of a pump which raises 9,200 gallons of water per minute through a height of 128.0 ft., when the loss of head in the pump and pipe amounts to 14 ft.
A pumping station wet well operates between 540- and 550-ft elevation. The pump curve is deϐined by the following points: 80 ft at zero ϐlow, 78 ft at 200 gpm, 65 ft at 800 gpm, and 50 ft at 1200 gpm. The pump discharge contains an equivalent of 50 ft of 6-in. pipe. The discharge pipe is 120-ft long and terminates at a splitter box, elevation 570. Using C=100, plot the pump curve and the corrected pump curve. Plot the pump discharge curves at each wet well elevation and for C=100 and C=140. What is the pump ϐlow at the low and high wet well elevations for newand old pipe?
Please list the symbols for pumps, actuators and different kinds of pressure valves.
