Consider the pipe network of Problem 8.189. Select a
pump suitable to deliver a total flow rate of 300 gpm through
the pipe network.
A fire nozzle is supplied through 300 ft of 3-in.-
diameter canvas hose (with e50:001 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 psi 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.
