An insulated piston-cylinder arrangement fitted with a linear spring initially contains 5 kg of water at 200 kPa with a quality of 10%. A supply line of steam at 500 kPa and 360 C is opened to allow 1 kg of steam into the piston-cylinder arrangement until the final pressure reaches 500 kPa. If the spring constant is 10 kN/m and the piston diameter is 300 mm, Determine: a) The work done during the process, in kJ. b) The final temperature of the steam, in C. Steam: 360 C, 500 kPa.
