Crude oil having a specific gravity of 0.80 and a viscosity of (6.0 times 10^{-5} mathrm{ft}^{2} /

Question:

Crude oil having a specific gravity of 0.80 and a viscosity of \(6.0 \times 10^{-5} \mathrm{ft}^{2} / \mathrm{sec}\) flows through a pumping station at a rate of \(10,000 \mathrm{barrels} / \mathrm{hr}\). The oil then flows through 120,000 ft of 24-in. ID, horizontal, commercial steel pipe, enters another pumping station at \(20 \mathrm{psig}\), and leaves at a discharge pressure equal to the discharge pressure of the previous pumping station. Calculate the discharge pressures and the power supplied to the crude oil at the second pumping station. See Fig. P8.74.
