Solve and Draw the figure completely labelled with all the notations used in your solution. 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 3 m above the hydrant and 18 m above the pump. Assuming a total frictional loss of 18.5 m from the pump to the base of the nozzle, and a loss in the nozzle of 10 per cent of the velocity head in the jet, and neglecting air resistance, what gage pressure at the pump is necessary to throw a stream 30 m vertically above the nozzle?
