A plant piping system takes a process stream ( ¼ 15 cP, ¼ 0:9 g/cm3 ) from one vessel at 20 psig, and delivers it to another vessel at 80 psig. The system contains 900 ft of 2 in. sch 40 pipe, 24 standard elbows, and five globe valves. If the downstream vessel is 10 ft higher than the upstream vessel, what horsepower pump would be required to transport the fluid at a rate of 100 gpm, assuming a pump efficiency of 100%?
