Question: A pump with a 5 . 5 - in impeller diameter characterized by the pump curves shown below is to be installed in the pipe

A pump with a 5.5-in impeller diameter characterized by the pump curves shown below is to be installed in the pipe system shown. The horizontal pipe system consists of a commercial steel pipe of 3-in diameter. The pump is been installed a distance of 40 ft from the pipe inlet. A temperature of 70F and standard atmospheric pressure may be assumed. The discharge is to be assumed as 500 gpm and friction factor as 0.0175.Estimate the NPSH available (at the pump inlet).
