Consider 0.15 kg of H 2 O (liquid and vapor in equilibrium) contained in a vertical pistoncylinder
Question:
Consider 0.15 kg of H2O (liquid and vapor in equilibrium) contained in a vertical piston–cylinder arrangement at 350 K, as shown in the sketch. Initially, the piston rests on the stops, and the volume beneath the 142.8-kg piston (area of 10 cm2) is 0.001306m3. The atmospheric pressure is 100 kPa, and the local gravitational acceleration is 9.80 m/s2. Energy is transferred to this arrangement until there is only saturated vapor inside. The piston moves without friction.
A. Show this process on T –V and P–V diagrams.
B. Determine the moving boundary work done by the H2O system.
