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
Heat Rate, WP/EP (Not sure if that is the correct formula)
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!
