Akeystone pipeline has a diameter of 36 inches and a design flow rate of 590,000 barrels per day of crude oil at 40ºc. estimate the pump horsepower required if the length of the pipe is 1.9 mile(s). the pipe material is new steel. for crude oil at 40ºc, take μ ≈ 0.0053 kg/m-s ÷ 47.88 = 0.111 slug/ft-s. the density, with sg = 0.86, is 0.86(1.94) = 1.67 slug/ft3. round the answer to the nearest whole number. take f ≈ 0.0155.
