Question

A sluice gate used to control the flow in a horizontal channel of unit width is shown in the figure.
A diagram of a sluice gate in a horizontal channel. The upstream depth is d1 = 1.0 m and the downstream depth is d2 = 0.2 m. Points 1 and 2 are marked upstream and downstream respectively.
It is observed that the depth of flow is 1.0 m1.0\text{ m} upstream of the gate, while the depth is 0.2 m0.2\text{ m} downstream of the gate. Assuming a smooth flow transition across the sluice gate, i.e., without any energy loss, and the acceleration due to gravity as 10 m/s210\text{ m/s}^2, the discharge (in m3/s\text{m}^3/\text{s}, up to two decimal places) passing under the sluice gate is ___________
