For the system below, let the pump exhaust gasoline at 65 gallons per minute to the
atmosphere through a 3-cm-diameter opening. When x = 3 m, y = 2.5 m and z = 2 m, the pipe
friction head loss along the entire length of the pipe has been shown to be hf = 3.7 V 2/(2g)
empirically, where V is the velocity in the pipe. Estimate the horsepower to be delivered by
the pump.
