A vertical cylinder fitted with a piston contains 0.02 m of wet steam at 180 °C and 90% quality. The piston is initially held in place by a pin. The piston has a mass of 100 kg and a cross-sectional area of 49 cm2. The ambient pressure is 100 kPa. The pin is removed, allowing the piston to move. After a sufficient period of time, the system comes to equilibrium, with the final temperature being 180°C. a) Determine the final pressure and volume of the steam, b) Calculate the work done by the steam during this process. (Answer: a) 300 kPa, 0.0782 m, b) -17.46 kJ) A vertical cylinder fitted with a piston contains 0.02 m of wet steam at 180 °C and 90% quality. The piston is initially held in place by a pin.
