6. (18 points) Super heated water enters an adiabatic turbine at 2.5 MPa and 350 °C at the inlet. After an internally reversible process, water leaves this turbine at 100

kPa. The flow rate of water is 5 kg/s. 2p) Is this expansion process in this turbine an isentropic process? 2p) Find the specific entropy and specific enthalpy of steam at the inlet. 8p) Find the specific entropy and specific enthalpy of water at the outlet. (7c). (6p) Calculate the power output of this turbine (in kW). You can ignore the change in kinetic and potential energy.
