A trapezoidal channel is to be designed for conveying 10,0000 ft^3 of water per minute. Determine the cross sectional dimensions of the channel if the bed slope is 1 in 1600, the side slopes are inclined at 45 degrees, and the cross section is to be minimized (R = y/2). Use C=90 in the Chezy formula.
