A fire pump delivers water through a 300 mm diameter main to a hydrant to which is connected a cotton rubber lined fire hose 150 mm in diameter terminating to a 25 mm diameter nozzle. The nozzle is 2.5m above the hydrant and 16m above the pump. Assuming frictional losses of 3m from the pump to the hydrant, 2m in the hydrant, 10m from the hydrant to the base of the nozzle, and the loss in the nozzle of 4% of the velocity head in the jet, to what vertical height, in m, can the jet be thrown if the gage pressure right after the pump is 550kPa? Round your answer to 3 decimal places. 25mm dia. nozzle 2.5m 13.5m 150mm dia. fire hose H 300 mm dia. main pipe
