1) In the figure below, assume the pipe diameter is 4-inches, (f = 0.035), Distance from BC is 18-feet, distance DE is 187-feet and ∆ z = 69-feet. The elevation of C is 14-feet above the lower water surface. If the pressure head @ C is to be no less than (–) 20 feet, what is the maximum flow rate that can be pumped? (Flow rate in GPM)
2) If the pump from the previous problem has 63% efficiency, what horsepower must be supplied to the pump in order to convey flow through the system?
(Kent = .8) Assume a submerged
exit.
