A trapezoidal channel is to be designed to carry a discharge of 75
/s at maximum hydraulic efficiency. The side slopes of the channel are 2H/1 V and the Manning n value is .030. a. If the maximum allowable velocity in the channel is 1.75 m/s, what should be the dimensions of the channel?

A rough timber flume ( = 0.016) with a cross section of a most efficient triangular section conveys water at a depth of 1.5 ft under uniform conditions. The channel has a bed slope of 0.001. Calculate the discharge.
