A fire pump delivers water through 15 cm main pipe to a hydrant to which is connected an 8 cm hose, terminating in a nozzle 2 cm in diameter. The nozzle, trained vertically up, is 1.60 m above the hydrant and 12 m above the pump. The head losses are: pump to hydrant 12 J/N; Nozzle: 6 % velocity head in the nozzle. If the gage pressure at the pump is 550 kPa to what height can the jet be thrown? Neglect air friction.

Question
A fire pump delivers water through 15 cm main
pipe to a hydrant to which is connected an 8 cm
hose, terminating in a nozzle 2 cm in diameter.
The nozzle, trained vertically up, is 1.60 m above
the hydrant and 12 m above the pump. The head
losses are: pump to hydrant 12 J/N; Nozzle: 6 %
velocity head in the nozzle. If the gage pressure at
the pump is 550 kPa to what height can the jet be
thrown? Neglect air friction.
