The following description applies to this problem and the next one. Two kilograms of water are inside a piston cylinder device as shown in the figure. Its pressure is equal to 100 kPa and its quality equal to 0.8546. The steam is heated until its final volume is one and a half times its initial volume. Its initial specific volume in m3/kg is closer to: 02.345 O 1.448 O 0.237 O 3.762 O 1.6941 0.856 O 1.991 0.001

The figure shows a cylindrical tank of 80 em in diameter which is fully filled with water. In order to increase the flow from the tank to the exit pipe on the left, an additional pressure is applied to the water surface by an air compressor to supply air to the upper air chamber of the tank. The external walls of the tank are exposed to the atmospheric conditions of the area. You are required to determine the hydrostatic conditions...
