Steam turbine is a device that extracts thermal energy from hot and high-pressure steam to do some mechanical work. Assume that steam enters an adiabatic turbine at 3MPa and 400°C

and leaves it at0.2MPA. Assume that kinetic energy and potential energy can be neglected. If the process is reversible, determine the entropy change and the phase of water leaving а.the turbine. b. What is the maximum power (in kW) delivered by the turbine given that the mass flow rate is 2kg/s?[50%]
