A steam power plant operates on an ideal reheat Rankine cycle between the pressure limits of 6 MPa and 20 kPa. Steam enters the high pressure turbine at (b) 6 MPa and leaves at 2 MPa. Steam is then reheated at constant pressure to same temperature. Heat is transferred to the steam in the boiler at a rate of 58,416 kJ/s. And the mass flow rate of steam through the cycle is 20 kg/s. The moisture content of the steam at the exit of the low-pressure turbine is not to exceed 8 per cent. Steam is cooled in the condenser by the cooling water from a nearby river, and the temperature rise is 12°C. Show the cycle on a T-s diagram with respect to saturation lines, and determine; i. the turbine inlet temperature; ii. the net power output and thermal efficiency; and ii the minimum mass flow rate of the cooling water required
