Problem 4: Open Channel Flow A circular pipeline stretches 202 miles from an initial elevation of 510 ft to a final elevation of230 ft. The pipe (D = 3.0 ft)

is made of concrete (A= 0.0030 ft). The open channel flow is steadyand uniform such that the pipe is half full. The fluid is water at 50° F. Part A Sketch a cross-section of the pipe flowing half full, then calculate its hydraulic radius, Rh [ft]. Part B Calculate the discharge, Q [ft/s].
