1. Consider a Non-Ideal Reheat-Rankine cycle operating with its boiler operating at 5 MPa and 600 °C and its condenser operating at 20 kPa. The isentropic efficiency of the turbines (n) are 88%. You may consider the pump operation ideal (n=100%). nt = Wta Wts = h3 - -hAa h3-h4s Reheat occurs at 800 kPa. The temperature after reheat is 500 °C. Find all three quantities. i) Net-work of the cycle ii) Heat added by the boiler iii) Overall cycle efficiency.
