Why unrestrained/free expansion of gas is an irreversible process?

The higher the value of heat transfer the faster will be the heat transfer according to Newton's law of cooling.

It is a measure of the quantity of the fluid that is being displaced from one place to other. This is an important parameter when designing

The pressure drop in the thermal system can be obtained by expanding the fluid in the expansion valve which produces thermodynamic work.

We come across a lot of properties and functions in Thermodynamics. These are divided mainly into path functions and point functions. All...

The efficiency of an irreversible heat engine is always less than the efficiency of a reversible engine operating between the same two

The T-s diagram is one of the most used plots in Thermodynamics. It is used to analyze vapor power cycles, gas power cycles, and
