Given data:
Exit temperature of air from compressor, T2 = 550 K
Exit temperature of gas from turbine, T4 = 800 K
Effectiveness of regenerator, ε = 0.8
We know that in a Brayton cycle with regeneration, the regenerator helps to increase the thermal efficiency of the cycle by recovering heat from the exhaust gas and transferring it to the compressed air before combustion. The temperature of the air entering the combustion chamber is increased due to this heat transfer.
To find the air temperature at the combustion chamber inlet, we can use the following formula:
T3 = T2 + ε(T4 - T2)
where T3 is the temperature of the air at the combustion chamber inlet.
Calculation:
Substituting the given values, we get:
T3 = 550 K + 0.8(800 K - 550 K)
T3 = 750 K
Therefore, the air temperature at the combustion chamber inlet is 750 K.
Conclusion:
Hence, option D is the correct answer.
Exit temperature of air from compressor, T2 = 550 K
Exit temperature of gas from turbine, T4 = 800 K
