A sewer of diameter D = 0.6 m has a bed slope of 1: 200. What is the possible maximum velocity of flow in this pipe? What is the discharge at this velocity? Take C= 55.

A 20-ft-wide rectangular channel carries a discharge of 400 cfs at a normal depth of 10 ft. If the roughness coefficient is 0.03, what shear stress in lb/ 1s imparted to the channel boundary by this flow?
