Figure below shows a seawater-retaining gate with a curved portion. When the water level gets to a certain height, the fluid forces acting on the gate open it, and the seawater passes through. The gate is 1m wide (into the page) and is to be designed so that the water depth does not exceed 2m. Determine the length L of the straight portion of the gate required to do this. The density of seawater is 1030 kg/m³. Gate 1 m Hinge 2 m
