Agas-turbine cycle with two stages of compression (intercooling) and two stages of expansion (reheat) is considered. the inlet air to the first compression stage is at 300 k. the compression efficiency in each stage is 0.8 and expansion efficiency in each stage is 0.85. the compression and expansion ratio in each stage is 3. the air is cooled to its initial temperature after the first compression and is reheated to the maximum temperature after the first expansion. the air is at the temperature of 1200 k leaving the combustor. consider one case without a regenerator and a case with a regenerator with effectiveness of 0.75.a) show the t-s diagram of the cycle. b) determine the back work ratio with and without generator. c) determine the thermal efficiency of the cycle with and without the generator.
