= Water flows into a tank and out through another pipe, as shown in the figure below. The water in the tank has a surface area, Asur f 5.6 m². At the bottom of the tank there is a door inclined at an angle = 25 degrees with respect to the horizontal. The door has a length L = 1.1 m and a width w=1 m (out of the page). The flowrate into the tank is Q₁ (t) flowrate out is Qo(t) = 0.05 m³/s At time t = Asurf = 0.26 m³/s and the 0, the water has a depth ho = 2.5 m. The density of water is p = 1000 kg/m³. Ө h(t) Qout
