2. Steam at 400C, 6 MPa enters an insulated turbine with a mass flow rate of 1.5 kg/s and leaves as a saturated mixture at 40C. The steam then enters an insulated flash chamber, which separates the steam into saturated liquid and saturated vapor at the same temperature. If the turbine produces 1200 kW of power, calculate a) The amount of liquid water that will be obtained in one hour, b) The isentropic efficiency of the turbine, c) The rate of entropy generation in the whole process. Show all the states of water involved in the problem on a T-s diagram. 2. Steam at 400C, 6 MPa enters an insulated turbine with a mass flow rate of 1.5 kg/s and leaves as a saturated mixture at 40C.
