Solved Problems on Heat Engines, Refrigerators and Heat Pump: Second Law and Entropy - Engineering Thermodynamics

Subject and UNIT: Engineering Thermodynamics: Unit II: Second Law and Entropy

A temperature scale which is independent of the properties of the substances that are used to measure temperature is called a thermodynamic temperature scale.

Subject and UNIT: Engineering Thermodynamics: Unit II: Second Law and Entropy

Carnot theorem states that "no heat engine operating in a cyclic process between two fixed temperatures can be more efficient than a reversible engine which is operating between the same temperature limits"

Subject and UNIT: Engineering Thermodynamics: Unit II: Second Law and Entropy

As all the processes in the Carnot cycle are reversible, it can be reversed. In this case, it becomes the Carnot refrigeration cycle.

Subject and UNIT: Engineering Thermodynamics: Unit II: Second Law and Entropy

It is also called constant temperature cycle.

Second Law of Thermodynamics

Subject and UNIT: Engineering Thermodynamics: Unit II: Second Law and Entropy

Practically, all thermodynamic processes are irreversible process.

Second Law of Thermodynamics

Subject and UNIT: Engineering Thermodynamics: Unit II: Second Law and Entropy

All processes are divided into two types on the basis of second law of thermodynamics.

Subject and UNIT: Engineering Thermodynamics: Unit II: Second Law and Entropy

The statements which can be proved with the help of reversible cycles are called corollaries of the second law of thermodynamics.

Subject and UNIT: Engineering Thermodynamics: Unit II: Second Law and Entropy

As we know, heat and work are mutually convertible.
