The rectangular gate shown in Figure 2.65 is intended to control the flow of seawater into a freshwater reservoir. If the freshwater has a density of 998 kg/m³, the seawater has a density of 1025 kg/m³, and the gate weighs 100 lb/meter (into the page), find the depth of seawater when the gate opens.
