The fire department needs information on friction losses occurring between a water main and an open fire hydrant. at maximum main pressure (85 psig), the water discharge rate is 1620 gpm through a 2.5-inch open fire hydrant. the water main, in which the velocity is very small, is situated 8 ft below the hydrant discharge point. determine the friction loss from the main to the discharge point. assume atmospheric pressure is 15 psia.
