A fire pump delivers water through a 150 mm main to a hydrant to which is connected a 75 mm hose, terminating in a 25 mm nozzle. The nozzle is is 1.5 m above the hydrant and 10 m above the pump. Assuming frictional losses of 3 m from the pump to the hydrant, 2 m in the hydrant, and 12 m from the hydrant to the base of the nozzle and a loss in the nozzle of 6% of the velocity of the head in the jet, to what vertical height can the jet be thrown if the gage pressure at the pump is 550 KPa
