Unformatted text preview: turbine at 7 MPa and 500 o C. The steam exits the turbine at 10 kPa and is cooled in the condenser by cooling water from a lake at 16 o C with a flow rate of 2000 kg/s through tubes. Show the cycle on a Ts diagram with respect to saturation lines and determine (a) the Cycle thermal efficiency, (b) the steam mass flow rate and (c) the cooling water exit temperature. 4. A steam power plant operates on an ideal reheat Rankine cycle. The steam enters the high pressure turbine at 8 MPa and 500 o C and then leaves at 3 MPa. The steam is then reheated at constant pressure of 3 MPa to 500 o C before it expands in a low pressure turbine to exit at 20 kPa. Determine the total specific turbine work and thermal efficiency of the cycle. Also show the cycle on a Ts disgram with respect to saturation lines....
