1. Oil (SG = 0.9), with a kinematic viscosity of 0.007 ft2 /s, flows in a 3-in.-diameter pipe at 0.01 ft3 /s. Determine the head loss per unit length of this flow.
2. Water flows through a 6-in.-diameter horizontal pipe at a rate of 2.0 cfs and a pressure drop of 4.2 psi per 100 ft of pipe. Determine the friction factor
