A steam power plant uses the ideal Regenerative Rankine cycle with single open feedwater heater where the steam enters the high-pressure turbine at 4 MPa and 300C. It partially expands to 600 kPa then some steam is extracted at this point. The remaining steam expands and 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. Neglect the condensate pump work.

Required information. The net work output and the thermal efficiency for the Carnot and the simple ideal Rankine cycles with steam as the working fluid are to be calculated and compared. Steam enters the turbine in both cases at 10 MPa as a saturated vapor, and the condenser pressure is 50 kPa. In the Rankine cycle, the condenser exit state is saturated liquid and, in the Carnot cycle, the boiler inlet state is saturated liquid. Draw the T-s diagrams for both cycles.

Consider a steam power plant, which can be modeled using the ideal reheat Rankine cycle. The steam entering the high- pressure turbine is at 6 MPa and 400 degrees C and leaves at 2 MPa. The steam is then reheated to 400 C at constant pressure, before it expands to 20 kPa in the low-pressure turbine. Calculate: (a) the turbine work output in kJ/kg (b) the thermal efficiency of the cycle

Find the net work.
