10.18 Afire nozzle is supplied through 300 ft of 3-in.-diameter canvas hose with e=0 001 ft. Water from a hydrant is supplied at 50 psig to a booster pump on board the pumper truck. At design operating conditions, the pressure at the nozzle inlet is 100 psig and the pressure drop along the hose is 33 psig per 100 ft of length. Calculate the design flow rate and the maximum nozzle exit speed. Select a pump appropriate for this application, determine its efficiency at this operating condition, and calculate the power required to drive the pump.
