For the system of Prob. 3.183, let the pump exhaust gasoline at 65 gal/min to the atmosphere through a 3-cm-diameter opening, with no cavitation, when x = 3 m, y = 2.5 m, and z = 2 m. If the friction head loss is hloss ≈ 3.7(V2/2g), where V is the average velocity in the pipe, estimate the horsepower required to be delivered by the pump.
