Water is the working fluid in a Carnot vapor power cycle. Saturate liquid enters the boiler at a pressure of 10 MPa, and saturated vapor enters the turbine. The condenser pressure is 6 kPa. Determine (i) the thermal efficiency, (ii) the back work ratio, (iii) the heat transfer to the working fluid in the boiler, and (iv) the heat transfer from the working fluid in the condenser. In part B of the problem, irreversibilities in the adiabatic expansion and compression processes cannot be neglected. If the states at the turbine and pump inlet remain unchanged, repeat parts (i-iv) for the modified Carnot cycle with NT= 0.80 and Np = 0.70. Finally, calculate the rate of entropy generation in modified Carnot cycle having irreversibilities.
