You must determine the pump pressure and power required to transport a petroleum fraction (µ = 60 cP, density = 55 lbm/ft3 ) at a rate of 500 gal/min from a storage tank to the feed plate of a distillation column. The pressure in the tank is 2 psig, and that in the column is 20 psig. The liquid level in the tank is 15 ft above ground, and the column inlet is 60 ft high. The piping system contains 400 ft of 6 in. sch. 80 steel pipe (new commercial steel), 18 standard elbows (flanged, welded elbows), and 4 globe valves (standard globe valves): a) Using the 3K Method for determining minor loss coefficients, calculate the pump horsepower required for flow in this entire system. b) Repeat the calculation using the equivalent L/D method
