Assuming the same length of pipe. Round your answer to the nearest diameter of commercially available Schedule 40 PVC pipe. (Google is your friend here) D pipe = 2.5 in 2) (25 points) Given the piping system shown below, calculate the Q ( in GPM ) conveyed between the two tanks. Assume e (or k) = 0.3 mm, water temperature = 20 o C. Also, assume hydraulically rough flow conditions. Account for all losses and show all work . Elevations shown below are in feet .
