Entropy
Entropy of system, is a measure of the avaialability of its energy. A system with high
entropy can do less useful work. This concept was formally used to define the second law
of thermodynamics.
Specific Entropy
Specific entropy of a system is the entropy of the unit mass of the system and has the
dimension of energy/ mass/temperature. The SI unit of specific entropy is J/(Kg . K).
Other units are:
- 1 KJ/kg,K= 1000 J/(Kg . K)
- 1 erg/g,K= 1E-4 J/(Kg . K)
- 1 Btu/lbm,F= 4186.8 J/(Kg . K)
- 1 cal/g,C= 4186.8 J/(Kg . K)
