A concrete sewer pipe is to be laid on a slope of 2.5% and must carry a maximum design discharge of 5 cfs. Also, it must carry a minimum discharge of 0.5 cfs with an acceptable cleaning velocity. What size pipe should be used?

It is desired to design a concrete storm sewer to carry a maximum discharge of 1.5
 /s on a slope of 3%. The pipe must also cany a minimum flow of 0.1
/s with an acceptable cleaning velocity. Determine the minimum pipe diameter to meet these requirements.
