Unformatted text preview: the turbine exit, ( , we apply the turbine efficiency: ) ( ) The turbine work becomes
( ) ( ) Thus, the Back Work Ratio (BWR) is defined as Regenerator Analysis:
To find , we apply the regenerator effectiveness: ( ) ( ) To find the heat transferred from the turbine exhaust gas to the compressor exit gas, apply the steadyflow
conservation of energy to the compressor gas side of the regenerator.

Apply the steadyflow conservation of energy to the heat exchanger for process 53, we obtain a result
similar to that for the simple Brayton cycle.
