A system of 1 kg of H2O at an initial condition of pl = 0.15 MPa and v1 = 0.6 m3 / kg undergoes a reversible process, which can be described by a straight line on the p–v diagram, to the final state of p2 = 15 MPa and T2 = 250°C. a. Find the heat and work interactions of this process. b. Find the entropy change of the system.
