4.) Steam undergoes an Isentropic process where it is initially at 1.30 MPa and 200 C then it expands to a pressure of 0.75 MPa, thus becoming wet steam. What is the dryness of the steam and the change in enthalpy for the process? • 100%, -2766.4 kJ/kg • 98.75, -68.94 kJ/kg • 200%, -2809.7 kJ/kg • 96.95%, -105.94 kJ/kg
