he below figure shows a pump that transfers a steady stream of 35◦API crude oil from an oil tanker to a refinery storage tank, both free surfaces being open to the atmosphere. The effective length—including fittings—of the commercial steel pipe is 6,000 ft. The discharge at point 4 is 200 ft above the pump exit, which is level with the free surface of oil in the tanker. However, because of an intervening hill, point 3 is at a higher altitude than point 4. Losses between points 1 and 2 may be ignored. The crude oil has the following properties: Density ρ = 53 lbm/ft 3 ; Viscosity μ = 13.2 cP; Vapour Pressure Pv = 4.0 psia CASE 1- Type Problem If the pipeline is Schedule 40 with a nominal diameter of 6 in., and the required flow rate is 506 gpm, what pressure P 2 is needed at the pump exit? Solve the problem first by manual calculations.

CASE 1- Type Problem
If the pipeline is Schedule 40 with a nominal diameter of 6 in., and the required flow rate is
506 gpm, what pressure P 2 is needed at the pump exit? Solve the problem first by manual
