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