Question: A rectangular channel of width 6 m has an initial flow velocity of 3 m / s with a depth of 2 m . This

A rectangular channel of width 6m has an initial flow velocity of 3 m/s with a depth of 2m. This
flow encounters a simultaneous reduction of width to 3m and a downward step. Assuming no
energy losses occur in this transition, find the specific discharge upstream and downstream, and
the smallest possible height of the downward step to maintain these flow conditions
