Oil of kinematic viscosity 1.05 x 10-5 ft2/s flows in turbulent regime with Reynolds Number Re = 105in a pipe of inside diameter 2¼-inches. What is the volume flow rate Q of oil in the pipe? Give your answer in gallons per minute (gal/min).
If the roughness of the pipe in Problem 1 is 1.25 x 10-4 ft while the rest of the data remains the same. What is the energy lost due to friction in 200 ft length of pipe? Give your answer in lb-ft/lb .
