Question No. 48 Civil | GATE 2017

A sluice gate used to control the flow in a horizontal channel of unit width is shown in the figure.

It is observed that the depth of flow is 1.0 m upstream of the gate , while the depth is 0.2 m downstream of the gate. Assuuming a smooth flow transition across the sluice gate, i.e, without any energy loss, and the acceleration due to gravity as 10 m/s2, the discharge (in m3/s, up to two decimal places) passing under the sluice gate is _______

Answer : 0.80 to 0.83
