Gas turbines used for power generation sometimes employ intercooling. show on a t-s diagram a typical gas turbine cycle employing intercooling. intercooling is done to improve plant efficiency. however it does mean the compressed air enters the combustion chamber colder than without intercooling. explain how that can still lead to increased thermal efficiency.
