A lubricating line has an inside diameter of 0.1 in. and is 30 in. long. If the pressure drop is 15 psi, determine the flow rate of the oil. Use the properties given in Problem 13.1.

Data From Problem 13.1

An oil with kinematic viscosity of 0.08 × 10^-3 ft²/s and a density of 57 lb_m/ft³ flows through a horizontal tube 0.24 in. in diameter at the rate of 10 gal/h. Determine the pressure drop in 50 ft of tube.
