Reheat factor is the ratio of_____________?
Correct answer: C. cumulative actual enthalpy drop for the stages to total is isentropic enthalpy heat drop
- A. isentropic heat drop to useful heat drop
- B. adiabatic heat drop to isentropic heat drop
- C. cumulative actual enthalpy drop for the stages to total is isentropic enthalpy heat drop
Explanation
Reheat factor equals the sum of the actual enthalpy drops in all turbine stages divided by the overall isentropic enthalpy drop. Because stage reheat increases the cumulative actual drop, the factor is slightly greater than one.
