3. A water vapor thermoelectric plant operates in the regenerative Rankine cycle with two open feed water heaters as shown in the figure. The plant maintains the turbine inlet at 10 MPa and 600 ° C, and operates the condenser at 5 kPa. Steam is drawn from the turbine at 0.6 and 0.2 MPa. The water comes out of both feed water heaters as a saturated liquid. The isentropic efficiency for the turbine and the pumps is 90%. For a flow of 20 kg / s in the boiler use software and obtain the power of the turbine, the power consumed by the pumps, the heat supplied to the boiler and the thermal efficiency for this cycle.
