A pump is to be installed in a straight horizontal pipe. The site is at an elevation of 20ft (essentially at sea level). The water temperature is 50F and the flow rate will be 5 cfs. The required NPSH is 15ft. Calculate how far (length) the pump can be located from the pumping reservoir so that the available NPSH is equal to the required NPSH. The pump will be place 10ft higher than the water surface in the reservoir. Assume the pump diameter is 12 inches. Assume a friction factor, f=0.0145.
