B1.08 to 1.10
-
C1.2 to 1.6
-
D1.6 to 2
Answer
Correct Answer: 1.02 to 1.06
Explanation
ConceptBecause cumulative heat drop across multiple stages slightly exceeds the single-step isentropic drop, the reheat factor is a bit greater than unity.
Typical valuesFor conventional steam turbines, RHF typically lies in the range 1.02 to 1.06.
Final Answer1.02 to 1.06
