B-A trapezoidal channel with (b=3M, 2= 2M, S=0,0016 Manning coefficient n=0,025) carries discharge of (12 m³/sec). Find the normal depth and velocity?

5) In a triangular channel, the velocity along the centre line at a depth of 0.2 m and 0.8 m is 0.7 m/s and 0.5 m/s, respectively. The triangular channel has dimension of 4 m by 1 m. Calculate the discharge in the channel.

The discharge in a rectangular channel of width 7m and max depth of 3m is 10 m3/s. The normal depth is 2.55m. Determine the depth of flow downstream of a section in which the bed rises by 0.5m over a distance of 1m.

In a triangular channel, the critical depth for a discharge of 1.2 m³/s is 1.3 m. The critical depth. for a discharge of 38.4 m³/s through the same channel would be: (b) 2 1m
