Water at 70°F passes through 0.75-in-internal diameter copper tubes at a rate of 0.4 lbm/s. Determine the pumping power per ft of pipe length required to maintain this flow at the specified rate. Take the density and dynamic viscosity of water at 70°F as p= 62.30 lbm/ft3 and u = 6.556x10-4 lbm/ft.s. The roughness of copper tubing is 5x10-6 ft. (Round the final answer to four decimal places.) The pumping power per ft of pipe length required to maintain this flow at the specified rate is W (per foot length).
