Water vapor enters a turbine at 6 MPa and 450°C and leaves the turbine at 100 kPa. Assuming an isentropic (constant entropy) process, determine the work out of the turbine in kW/kg and the exit temperature of the fluid and quality if applicable. If the turbine has an isentropic efficiency of 60%, determine the work out of the turbine and the exit temperature of the fluid and quality if applicable.
