A fire pumper pumps 150 gpm of water from a fire hydrant through 250 feet of 2.5" c=120 fire hose. 50 feet of the hose are on the suction side of the pump with the remaining 200 feet are on the discharge side. The hydrant and the pump are at the same elevation and the pressure in the hydrant is 20 psi. The velocity head in the source main is negligible. The discharge is through a 1.5 inch nozzle at an elevation 60 feet above the pump. The minor losses are negligible. Atmospheric pressure is 14.6 psia and the LVP is 1.5 ft h2o. Sketch the system drawing in the energy lines and showing the EGL elevations at the hydrant, the pump suction and discharge,and the nozzle. Calculate the suction head, discharge head, total head, and NPSH for the pump. What flow would have to be pumped to make the suction head 30ft?

(100 points) Water at 25°C is pumped at a rate of 0.075m'/s from a reservoir 20m above a pump to a free discharge (this means discharged to atmosphere) 35m above the pump. The pressure on the intake side of the pump is 150kPa and the pressure on the discharge side of the pump is 450kPa. The pipe between the reservoir and the pump is 3 meters of 5in diameter cast iron. From the pump to the discharge the pipe is...
