The figure below shows a portion of a fire protection system in which a pump draws 1500 gal/min of water at 50°F from a reservoir and delivers it to point B. The energy loss between the reservoir and point A at the inlet to the pump is 0.65 lb-ft/lb. Specify the required depth h to maintain at least 5.0 psig pressure at point A. If we assume that the pressure at point A is 5.0 psig, calculate the power delivered by the pump to the water to maintain a pressure of 85 psig at point B. Energy losses between the pump and point B total 28.0 lb-ft/lb. Flow 8-in Schedule 40 steel pipe 25 ft Flow Pump 10-in Schedule 40 steel pipe Pump Power hp.
