In a gas turbine, reheating is preferred over regeneration to

Question

Direction: Each of the next consists of two statements, one labeled as the ‘Assertion (A)’ and the other as carefully and select the answers to these item using the codes given below:

Codes:

1. Both A and R are individually true and R is the correct explanation of A
2. Bothe A and R are individually true but R is not the correct explanation of A
3. A is true but R is false
4. A is false but R is true

Assertion (A): In a gas turbine, reheating is preferred over regeneration to yield a higher thermal efficiency

Reasons (R): The thermal efficiency given by the ratio f the difference of  work done by turbine (W_t) and work required by compressor (W ) to heat added (Q_A) is improved by increasing the W_t keeping W_c and Q_A constant in reheating whereas in regeneration Q_A is reduced keeping W_t and W_C constant.
