1. The problem statement, all variables and given/known data 2. Relevant equations Heat added, Qa (This I'm not sure how since the steam passed through a reheater before it enters the HPT. That is what I understand based on the problem above) Work Net, Wnet Efficiency, Wnet/Qa Heat Rate, WP/EP (Not sure if that is the correct formula) 3. The attempt at a solution First I made a T-S Diagram Based on the diagram above, I got all these enthalpy values. h1 = h @ 3 MPa & 370C h2 = h @ 0.7 MPa & s1 h3 = h @ 0.7 MPa & 500C h4 = hf4 +x hfg4 (All values, 0.007 MPa) where x = (s4 - sf4)/sfg4 h5 = hf @ 0.007 MPa h6 = vf5 (P6-P5) WP1 = h6-h5 ha = h @ 3 MPa and 500C The WNet that I got is, 1485.491 For the Qa = (ha-h6) + (h3-h2) = 3959.022 Eff = .3752 Was not able to solve Heat Rate. ------------- I can't seem to understand how the answers shown in the problem was got. Please enlighten me. Thanks in advance!
