WebEfficiency of the Otto Cycle vs. Carnot Cycle • There are only two temperatures in the Carnot cycle • Heat is added at T H • Heat is rejected at T L • There are four … WebTo determine the cycle thermal efficiency η vs. r p and the total net power of W ˙net vs. r p relationships, we need to first calculate the relevant parameters for the Brayton cycle. These parameters include the compressor and turbine efficiencies, the pressure ratio, and the temperatures at all points in the cycle.
