List, in order of importance, ten key elements of analysis in the design of any piping system.
A horizontal pipeline consists of 225 feet of straight pipe, (6) 90° elbows, (1) gate valve, (1) swing check valve and (12) unions/welds. The pipe is 6” diameter, schedule 40. If the pipeline transports 68 lbm/sec of a fluid with a density of 58 lbm/ft3, viscosity of 3 cP, and discharges to an open pit, find the ideal water (hydraulic) horsepower of the pump. If the pump and motor efficiencies are 68% and 92%, determine the brake horsepower of the prime mover.
If the system above draws the fluid from another open pit at an elevation of 10’ below the pump centerline using the same diameter pipe with one lift check valve and a single 90° elbow prior to the pump suction and the fluid has a vapor pressure of 1 psi, find the NPSHA. What minimum NPSHR would you specify for the pump and why?
Size a control valve for the above system to provide a normal ΔP of 15 psi.
