Reheating in a gas turbine
A. Increases the thermal efficiency
B. Increases the compressor work
C. Increases the turbine work
D. Decreases the thermal efficiency
Answer: Option A
Solution(By Examveda Team)
Reheating is applied in a gas turbine in such a way that it increases the turbine work without increasing the compressor work or melting the turbine materials.When a gas turbine plant has a high pressure and low pressure turbine a reheater can be applied successfully.

increase work output and decrease thermal efficiency so answerr is d
ans is c not a
Wrong, reheating increases the mean temperature of heat rejection thus decreases thermal efficiency and increases specific work output.
answer is C...thermal efficiency gets increased only when optimum reheat pressure is used...
Efficiency in a gas turbine only increases when regeneration is involved. reheating increases output work by trubine only.
