A pump delivers water at 200C between a reservoir and a water tank that is 75[ft] higher than the reservoir. The suction side of the system consists of a cast iron pipe of 1[ft]diameter with a strainer (Ks= 2.5) and four 90-degree bends at R/D= 5. The discharge side of the system includes a 1000[ft] long commercial steel pipe with 12” diameter followed by a gate valve. The NPSH required for the pump is 10[ft], and the design discharge is 10[cfs]. Assume the strainer coefficient includes the entrance loss coefficient. Determine the maximum allowable length of the pipe on the suction side of the system if the pump is to be located at 5[ft] above the reservoir water surface.
