What is Thermal Efficiency - Definition

Thermal Efficiency. An ideal heat engine is an imaginary engine in which energy extracted as heat from the high-temperature reservoir is converted completely to work. But according to the Kelvin-Planck statement such an engine would violate the second law of thermodynamics because there must be losses in the conversion process.The net heat added to the system must be higher than the net work ...
