Problem 62HP
A piston/cylinder arrangement is loaded with a linear spring and the outside atmosphere. It contains water at 5 MPa, 400°C, with the volume being 0.1m3, as shown in Fig. P2.62 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 and the final state (T2, v2) and plot the P–v diagram for the process.

A piston/cylinder arrangement is loaded with a linear spring and the outside atmosphere. It contains water at 5 MPa, 400°C, with the volume being 0.1m3, as shown in Fig. P2.62 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 and the final state (T2, v2) and plot the P–v diagram for the process.
We are required to find the mass of water and the final state (T2, v2) and plot the P–v diagram for the process.
