Clausis inequality refrigeration
WebAfter deriving Clausius inequality for all cycles: (1) ∑ i = 1 n Q i T i ⩽ 0 I've seen some books (Fermi, Thermodynamics is an example) doing what follows: If the cycle is reversible, we can consider the inverse cycle, and the only difference will be the opposite sign of the heats. So: (2) ∑ i = 1 n − Q i T i ⩽ 0 ∑ i = 1 n Q i T i ⩾ 0 WebThe Clausius inequality forms the basis for the definition of a new property called entropy. As can be seen in the equation above, for an internally reversible process the cyclic integral of δQ / T is zero. A quantity whose cyclic integral is zero depends on the state only
