WebHeat Engines in the Real World. All undergraduate physics students are taught the Carnot cycle as an example of a thermodynamic engine. The Carnot cycle is optimized for efficiency but unfortunately yields zero power, and is therefore not very useful in reality. However, it’s analysis is mathematically elegant. WebTo determine the efficiency, we need to find Q H. Hence, we need to use the heat transferred and the work to calculate it. Then, we can use the efficiency formula to calculate efficiency, using heat lost Q H and work. Q H = Q C + W = 1920 + 400 = 2320 J η = W Q H = 400 / 2320 = 0. 1724 η % = 0, 1724 · 100 = 17, 24 %.
