A1. Superheated vapor at 3 bar, 200 C is stored in a rigid tank with constant volume. The tank is then cooled down. The pressure at final state is 2.5 bar. If the volume of the tank is 2 m, determine: a) the mass of steam stored in the tank (in kg) BEFORE cooling; b) the quality of steam AFTER cooling; and c) the mass of water condensed in the tank (in kg) AFTER cooling. (2 marks) (5 marks) (1 mark) A2. A 2 m sealed rigid cylinder contains nitrogen with pressure in 10 bar. The nitrogen is then heated up from 25 C to 65 C. Given that the gas constant of nitrogen (R) = 296.823 J/kgK. Determine: a) the mass (in kg) of nitrogen in the cylinder; and b) the pressure (in bar) of the cylinder after heating.
