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...
