Q35. An irrigation channel of trapezoidal section having side slope s 3 horizontal to 2 vertical is to carry a flow of 10 cumec on a longitudinal slope of 1 in 5000. The channel is to be lined for which the value of friction coefficient in Manning's formula is n = 0.012. Find the dimensions of the most economic section of the channel.
