Our aim is to calculate the efficiency of a gas turbine by assuming it operation can be modeled as a Carnot cycle. The kerosene (jet fuel) combustion is modeled as a hot reservoir at 2000K. The atmosphere is the cold reservoir. Calculate the efficiency of this ideal and reversible engine. Can any real engine operating between the two reservoirs be more efficient than this engine?
