Steam at 1 MPa, 630.2oC, expands in an insulated piston cylinder assembly to 0.01 MPa. Determine the maximum work (kJ) done during the process if the initial volume is 0.126 m3.
Steam at 1 MPa, 567.9oC, expands in a turbine to 0.01 MPa. If the process is isentropic, find the work per unit mass (kJ/kg) produced by the turbine.
Steam at 1 MPa, 556.4oC, expands in a turbine to 0.01 MPa. If the process is isentropic, find the specific enthalpy (kJ/kg) at the exit of the turbine.
