Question: A weir 0.78 m in height is built across the floor of a 4-m-wide rectangular channel. If the water depth just upstream of the weir

A weir 0.78 m in height is built across the floor of a 4-m-wide rectangular channel. If the water depth just upstream of the weir is 2.00 m, what is the flow rate in the channel? Neglect friction loss and the velocity head upstream. Also determine the flow rate if the velocity head is not neglected.
