An engineer is inspecting a rectangular drainage valve on the floor of a swimming pool. The diagram below shows the layout of the valve, which has dimensions of 0.25 m0.25\text{ m}0.25 m by 0.12 m0.12\text{ m}0.12 m.
The water pressure acting on the valve at the bottom of the pool is 24.0 kPa24.0\text{ kPa}24.0 kPa.
Calculate the total downward force exerted by the water on this rectangular drainage valve.
