A rectangular weir is designed to span the full width of a rectangular channel with B=L=2.5 m. (where B and L are the channel width and the weir width respectively) to pass a flow rate of 0.405 m³/sec and to maintain an upstream flow depth in the channel equals 0.815 m. Assume C₂ = 0.625 which is valid for < 5.0, where h is the flow depth over the crest of the weir and w is the weir height. The weir height is in the range of: O (0.65 -0.675) m O (0.60 -0.625) m

Question
A rectangular weir is designed to span the full width of a rectangular channel with B=L=2.5
m, (where B and L are the channel width and the weir width respectively) to pass a flow rate
of 0.405 m³/sec and to maintain an upstream flow depth in the channel equals 0.815 m.
Assume C₁ = 0.625 which is valid for <5.0, where h is the flow depth over the crest of the
weir and w is the weir height.
The weir height is in the range of
O (0.65 -0.675) m
O (0.60 -0.625) m
O (0.675 -0.70) m
O (0.625 -0.65) m
