Relation among enthalpies of steam entering & leaving turbine - Thermodynamics

Q.  Considering only heat loss (Qloss) in the expansion process at the turbine, what is the correct relation among enthalpies of steam entering and leaving the turbine (h1 and h2 respectively), turbine work (WT) and heat loss (Qloss)
- Published on 19 Aug 15

a. h1 = h2 – WT – Qloss
b. h1 = h2 + WT – Qloss
c. h1 = h2 + WT + Qloss
d. none of the above

ANSWER: h1 = h2 + WT + Qloss
