1.Find the critical depth for a flow of 6 m3/s in a triangular channel; one side of the channel is vertical and the other side makes an angle of 30° with the horizontal.
2.The rate of flow through a trapezoidal open channel is 20 m^3/s and the mean velocity of flow is 1m/s . the side slope is 1:1 and the bed slope is 1 in 5000. Assume Chezy's constant C as 60, find the bottom width and the depth of water channel.
