WebThe engine we have just described is called a Carnot engine, and is the simplest conceivable device capable of converting heat energy into useful work. Figure 6.3: An ideal-gas Carnot engine. For the specific case of an ideal gas, we can actually calculate the work done per cycle, and, thereby, verify Equation ( 6.201 ). WebNov 22, 2024 · The efficiency of the Carnot engine is defined as the ratio of network done per cycle by the engine to heat absorbed per cycle by the working substance from the source. The efficiency is given by. η = W Q 1 = Q 1 − Q 2 Q 1 = 1 − Q 2 Q 1. Where W = Work, Q 1 = Amount of heat absorbed, Q 2 = Amount of heat rejected. As Q 2 Q 1 = T 2 T 1.

WebA heat engine can only convert part of the energy it received from the source to work. A certain amount of heat is dissipated to the sink as waste heat. The fraction of the heat input that is converted to net work output is a measure of the performance of a heat engine and is called the thermal efficiency(η th). In general, the efficiency (or ...
