Example of efficiency of heat engine

The maxium possible efficiency of a heat engine is

A : Efficiency of heat engine can neve be 100%. R : Second law of thermodynamics puts a limitaion of the efficiency of a heat engine.

Relationship between efficiency of heat engines and coefficient of performance.

A heat engine works between source and sink temperatures 150°C and 30°C respectively.The efficiency of heat engine may be

What would be the efficiency of the heat engine diagramed as shown below?

A scientist says that the efficiency of his heat engine which operates at source temperature 127^(@)C and sink temperature 27^(@)C is 26% , then

A scientist says that the efficiency of his heat engine which operates at source temperature 127^(@)C and sink temperature 27^(@)C is 26% , then

A scientist says that the efficiency of his heat engine which operates at source temperature 127^(@)C and sink temperature 27^(@)C is 26% , then

Define thermal efficiency of a heat engine.

Assertion : The efficiency of a heat engine can never be unity. Reason : Efficiency of heat engine is fundamental limitation given by first law of thermodynamics.
