A channel is closed by a rectangular gate shown in the Figure below. The gate which is hinged at the red circle in the figure is 7 m high and 1 m wide. It has seawater to the left to a depth of 7 m above the baseline and on the right has freshwater to a depth of 9.5 m above the baseline. The density of seawater is 1025 kg/m2, and density of freshwater is 1000 kg/m. Calculate the positive...
