An aquarium tank in an oceanarium has a length of 45 m45\text{ m}45 m and a width of 24 m24\text{ m}24 m. The water in the tank has a depth of 12 m12\text{ m}12 m and a density of 1025 kg/m31025\text{ kg/m}^31025 kg/m3.
Calculate the mass of water in the tank.
The pressure at point M, halfway down a large viewing window, is 75 kPa75\text{ kPa}75 kPa more than atmospheric pressure. Calculate the depth of M below the surface of the water (taking g=9.8 m/s2g = 9.8\text{ m/s}^2g=9.8 m/s2).
The viewing window is 28.5 m28.5\text{ m}28.5 m wide and 6.4 m6.4\text{ m}6.4 m high. Calculate the net outward force exerted by the water on this window. Assume that the pressure at M is the average pressure over the entire window.
