In this article, (and video above), we calculate the capacity of a concrete stormwater pipe that forms part of the Fluid Mechanics section of the FE Exam.
Question:
A concrete stormwater pipe is 500 feet long and has a pipe diameter of 36 inches. The inlet elevation is 165 feet and the outlet elevation is 160 feet. The Manning roughness coefficient, assumed to be constant with depth of flow, is 0.012.During heavy rainfalls, the stormwater pipe flows full with no surcharge.
During heavy rainfalls, the capacity of the stormwater pipe is most nearly:
