More effective way of increasing efficiency of Carnot engine where T₁ is source and T₂ is the sink is:

Explanation:

The efficiency of the Carnot engine is given by:

\(\eta = \frac{{{T_H} - {T_L}}}{{{T_H}}} = 1 - \frac{{{T_L}}}{{{T_H}}}\)

From the above formula, we know that efficiency is varied by:

• Decreasing the value of Temperature T_L
• Keeping constant the value of T_H

​

• The efficiency of the Carnot cycle is the function of the source and sink temperature.
• Carnot cycle efficiency depends upon the temperature range of operation.
• The efficiency of the Carnot engine is increased by decreasing the lower temperature and increasing the higher temperature but more effects on the efficiency of the Carnot cycle is by decreasing lower temperatures as compared to an increase in higher temperature.
