It is desired to design a trapezoidal channel with a bottom width of 10 ft and 1V/2H side slopes. Sieve analyses have revealed a grain size distribution which results in an allowable shear stress of 0.5 lb/ on the bed and a Manning n value of 0.03. If the channel is designed to run at a normal depth of 5 ft, what will be the resulting discharge?
