Answer to Question #120760 in Molecular Physics | Thermodynamics for Abhishek

Question

For a heat engine working between tem peratures T1 and T2, show all the steps of Carrot cycle on a T-S diagram. Hence calculate the efficiency of the engine.

Answer 1

A>B: Isothermal expansion;

B>C: Adiabatic expansion;

C>D: Isothermal compression;

D>A: Adiabatic compression.

The efficiency is

$$\eta=\frac{T_2-T_1}{T_2}.$$
