A fire protection system is supplied from a water tower with a bent pipe as shown in the figure. The pipe friction f is 0.03. Ignoring all minor losses, the maximum discharge Q in the pipe is 25 m 4 d = 100 mm 150 m Q
A pump is installed to deliver water from a reservoir of surface elevation zero to another of elevation 290 ft. The 10-in-diameter suction pipe (f=0.022) is 90 ft long, and the 8-in-diameter discharge pipe (f=0.028) is 4900 ft long. The pump characteristic is defined by hy=365–20Q? where hp, the pump head, is in feet and Q is in cubic feet per second. Compute the rate at which this pump will deliver water under these conditions.
Two reservoirs, A and B, are connected together by the two pipes with a pump between them. Assuming that the head loss in the pipes is given by hi = 0.015(L/d)(V/2g), where "L" is the length of pipe in feet and "d" is the pipe diameter in feet, determine (a) the velocity in each pipe, (b) the head added by the pump, and (c) the horsepower that must be supplied to the water to pump 2.5 cfs from the lower to the upper reservoir?
