Figure P2-81 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 1 m wide (into the page) and is to be designed so that water depth does not exceed 2 m. Determine the length L of the straight portion of the gate required to do this.
