Question

A vertical piston-cylinder apparatus contains 0.295 kg of water at a pressure of 0.04 bar that occupies a volume of 0.5 m3. Initially, the piston is resting on a set of stops. Then, heat transfer occurs and the pressure increases until the piston begins to move upward. The heat transfer continues until the volume expands to 0.75 m3. Neglect the mass of the piston and take the atmospheric pressure above the piston as 1 bar. a) Show the process on a P-v diagram (including the saturation dome). b) Determine the final temperature (°C). c) Determine the work performed by the water (kJ), d) Determine the heat transfer to the water (kJ).

Answer 1

Answer:

Explanation:

The concept of workdone in an Isochoric and Isobaric process is applied, the use of the steam table is also applied and the detailed steps and analysis is shown in the attached file.
