What is the total work done in Carnot cycle?

Question

Accepted Answer

The total work done in Carnot cycle is equal to the area enclosed by the cycle on a PV diagram.

The Carnot cycle is a theoretical thermodynamic cycle that consists of four reversible processes: isothermal expansion, adiabatic expansion, isothermal compression, and adiabatic compression.
The total work done in the cycle is equal to the difference between the work done during the isothermal expansion and the work done during the isothermal compression.
The work done during the isothermal expansion is given by W1 = Q1, where Q1 is the heat absorbed from the high-temperature reservoir.
The work done during the isothermal compression is given by W2 = -Q2, where Q2 is the heat rejected to the low-temperature reservoir.
Therefore, the total work done in the Carnot cycle is W = Q1 - Q2.
The efficiency of the Carnot cycle is given by eta = 1 - (T2/T1), where T1 is the temperature of the high-temperature reservoir and T2 is the temperature of the low-temperature reservoir.
The Carnot cycle is a theoretical ideal cycle and cannot be achieved in practice, but it provides a benchmark for the maximum efficiency that can be achieved by any heat engine.
