Oil (SG=0.82) entering a pump through an 8-inch diameter pipe at 4 psi has a flow rate of 3.5 cfs. It leaves the pump through a 4-inch diameter pipe at 15 psi. Assuming that the suction and discharge sides of the pump are at the same elevation, find the horsepower delivered to the water by the pump (550 lb.ft/s = 1 HP). Illustrate the problem and show your complete solution.
