A 2 1⁄2 - in. fire hose discharges water through a nozzle having a jet diameter of 0.97 in. the lost head in the nozzle is 5 percent of the velocity head in the jet. If the gage pressure at the base of the nozzle is 60 lb. per sq. in.: (a) compute the discharge in gallons per minute (1ft3 = 7.48gal); (b) what is the maximum horizontal range to which the stream can be thrown (neglecting air resistance)? (c) what is the maximum possible theoretical height that the jet can reach and at what angle?

Question
A 2 1⁄2 - in. fire hose discharges water through a nozzle having a jet diameter of 0.97 in. the lost head
in the nozzle is 5 percent of the velocity head in the jet. If the gage pressure at the base of the nozzle is 60 lb.
per sq. in.: (a) compute the discharge in gallons per minute (1ft3 = 7.48gal); (b) what is the maximum horizontal
range to which the stream can be thrown (neglecting air resistance)? (c) what is the maximum possible
theoretical height that the jet can reach and at what angle?
