A trapezoidal channel has a bed width of 10 ft and side slopes 2: 1. The channel is paved with smooth cement surface of
 = 0.011. If the channel is laid on a slope of 0.0001 and carries a uniform flow of depth 2 ft, determine the discharge.

Water flows uniformly in a 2-m-wide rectangular channel at a depth of 45 cm. Find the flow rate in
 /s; discuss the results for the following cases.

a. The channel slopes 25 cm/km and n = 0.025

b. The channel slopes 5 cm/km and n = 0.025

c. The channel slopes 25 cm/km and n = 0.05
