A rock bed(at 70 C) consists of 6000 kg granite. A house with mass of 12000 kg wood and 1000 kg iron is at 15 C. They are brought to a uniform final temperature. Find the irreversibility of the process, assuming an ambient temperature of 15 C.

A 2-kg piece of iron is heated from temperature 25 C to 400 C by a heat source which is at 600 C. What is the irreversibility in the process?

A heat exchanger increases the availability of 3 kg/s water by 1650 kJ/kg by using 10 kg/s air which comes in at 1400 K and leaves with 600 kJ/kg less availability. What is the irreversibility?

If two streams with equal temperature are mixing, then the entropy generation number becomes

Entropy generation number can be given by

The decrease in availability or lost work is proportional to

Heat transfer through a finite temperature difference is equivalent to the destruction of its exergy.

A thermodynamically efficient process would involve exergy loss with rate of entropy generation.

The quantity [To*( Ssystem + Ssurroundings)] represents an increase in

For irreversibility, same expression applies to both flow and non-flow processes.

For a non-flow process between equilibrium states, when the system exchanges heat only with the environment

Irreversibility(I) is also called

The actual work done by a system is always than the reversible work, and the difference between the two is called of the process.
