Consider an actual regenerative Rankine cycle with one open feed water heater. For each kg steam entering the turbine, if m kg steam with a specific enthalpy of h1 is blade from the turbine, and the specific enthalpy of liquid water entering the heater is h2, then h3 the specific enthalpy of saturated liquid leaving the heater is equal to
-
- mh1 – (h2 – h1)
- h1 – m(h2 – h1)
- h2 – m(h2 – h1)
- mh2 – (h2 – h1)
Correct Option: C
From energy balance (l – m)h2 + mh1 = h3
h3 = h2 – m(h2 – h1)
