# Question

A piston/cylinder arrangement is loaded with a linear spring and the outside atmosphere. It contains water at 5 MPa, 400C with the volume being 0.1 m3. If the piston is at the bottom, the spring exerts a force such that Plift 200 kPa. The system now cools until the pressure reaches 1200 kPa. Find the mass of water, the final state (T2, v2) and plot the P–v diagram for the process.
