A cement lined rectangular channel 6.0 m wide carries water at the rate of 11.0
/s. Determine the critical depth and the critical velocity.

A broad-crested weir of a height h is placed in a channel of width b. If the upstream depth is y 1 and the upstream velocity head and frictional losses are neglected, develop a theoretical equation for the discharge in terms of the upstream depth of flow. Assume the flow over the broad-crested weir to be critical.
