1 Relevant Steam Property Tables are provided on Pages 3 to 5 of this paper. A steam/water mixture is contained in a vertical cylinder by a 100 mm diameter freely movable frictionless thin piston. The cylinder is fitted with a set of stops 40 mm above the cylinder base. Initially at State 1, the piston remains in equilibrium 10 mm above the cylinder base while the steam/water mixture is at a pressure of 1.5 bar with a dryness fraction of 0.25. (a) Find the mass of the steam/water mixture. (6 Marks) The steam/water mixture is then slowly heated until the piston just reaches the stops at State 2. contains (b) Using appropriate calculations and reasoning, show that the cylinder superheated steam at State 2. (6 Marks) The contents of the cylinder are further heated to increase the pressure to 3.0 bar at State 3. (c) Draw the entire heating process on a T-v diagram, indicating all states involved. (3 Marks) (d) At State 3, determine the steam temperature and the force exerted by the stops on the piston. (12 Marks) (e) Calculate the total work done by the contents in the cylinder from State 1 to State 3. (8 Marks) (Total 35 Marks) Page 1 of 5
