Draw a schematic diagram of each problem with labels of states of a substance; Assign STATE 1 at the inlet of a high-pressure turbine. The states must be arranged in a chronological order; Plot each cycle in a t-s diagram with thestates consistent to the states assignment in the schematic diagram; A reheat-regenerative Rankine cycle receives steam at 8.0 MPa, 300 0C and exhaust at 0.01 MPa. Steam is extracted at 2.0 MPa for CFWH and the remainder for reheating. The reheated steam enters the 2nd stage turbine at 1.5MPa and expands to 1.0 MPa where more steam is extracted for OFWH. The remainder expands to the condenser pressure of 0.01MPa. Feedwater from low pressure regenerative heater leaves the CFWH at 207 0C and mixes with the feedwater. Determine the percentages of the extracted steam and the cycle thermal efficiency.
