    An irrigation channel

    (solved), A most efficient trapezoidal section is required to give a maximum discharge of 21.5 m3/s of water. The slope of the channel bottom is 1 in 2500. Taking C = 70 m1/2/s in Chezy’s equation, determine the dimensions of the channel. Also determine the value of Manning’s n, taking the value of velocity of flow as obtained for the channel by Chezy’s equation
