Water is the working fluid in an ideal regenerative Rankine cycle with one open feedwaer heater. Superheated vapor enters the first-stage turbine at 16 MPa, 560oC, and the condenser pressure is 8 kPa. The mass flow rate of steam entering the first-stage turbine is 120 kg/s. Seam expands through the first-stage turbine to 1 MPa where some of the steam is extracted and diverted to an open feedwater heater operating at 1 MPa. The remainder expands through the second-stage turbine to the condenser pressure of 8 kPa. Saturated liquid exits the feedwater heater at 1 MPa. Determine

(a) the net power developed in kW.

(b) the rate of heat transfer to the steam passing through the boiler, in kW.

(d) the mass flow rate of condenser cooling water, in kg/s, if the cooling water undergoes a temperature increase of 18oC with negligible pressure change in passing through the condenser.

(e) Now USING EES but include in the analysis that each turbine stage and pump has an isentropic efficiency of 85%.
