A hollow cylinder with closed ends is 300mm diameter and 450mm high, has a mass of 27kg and has a small hole in the base. It is lowered into water so that its axis remains vertical. Calculate the depth to which it will sink, the height to which the water will rise inside it and the air pressure inside it. Disregard the effect of thickness of the walls but assume that it is uniform and that the compression of the air is isothermal. Atmospheric pressure = 101.3kPa.
