A partially open sluice gate discharges water into a rectangular channel. The tail water depth in the channel is 3m and Froude number is 1/2√2. If a free hydraulic jump is to be formed at downstream of the sluice gate after the vena contracta of the jet coming out from the sluice gate, the sluice gate opening should be (coefficient of contraction Cc = 0.9)
