3.) A steam power plant uses the ideal Reheat-Regenerative Rankine cycle where the steam enters the high-pressure turbine at 4 MPa and 300C. It partially expands to 600 kPa where some steam is extracted for feedwater heating while the rest is reheated to the same temperature. After expanding again, it enters the condenser at 10 kPa. Sketch the schematic diagram and the TS diagram with labeled points, and solve for mass taken for feedwater heating, Qa, Qr, Wt, Wp, Wnet, thermal efficiency, and Steam rate.

Consider a regenerative power cycle with an open feedwater heater. water vapor enters the turbine at 8.0 MPa, 480°C and expands to 0.7 MPa where part of this vapor is extracted and presented to the open feedwater heater operating at 0.7 MPa. The rest of the steam expands in the second stage of the turbine to the condenser pressure of 0.008 MPa. The condenser outlet is saturated liquid at 0.7 MPa. The isentropic efficiency of each turbine stage is 85% and each pump operates isentropically. If the net power of the cycle is 100 MW, determine:1.Thermal performance and2. The mass flow of steam entering the first stage of the turbine, in kg/h.
