A fire pump delivers water through a 300 mm diameter main to a hydrant to which?

: is connected a cotton rubber lined fire hose 100 mm in diameter terminating to a 25 mm diameter nozzle. The nozzle is 2.5 m above the hydrant and 16 m above the pump. Assuming frictional losses of 3m from the pump to the hydrant, 2m in the hydrant, 10 m 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 can the jet be thrown if the gage pressure right after the pump is 550 KPa?

    Loses in pressure CANNOT be expressed in m.

    Therefore your question as stated is nonsense.
