WebMar 20, 2024 · Clausius Inequality Question 1 Detailed Solution Concept: Clausius inequality states that ∮ d Q T ≤ 0 It provides the criteria for the reversibility of a cycle. If ∮ d Q T = 0, the cycle is reversible, ∮ d Q T < 0, the cycle is irreversible and possible ∮ d Q T > 0, The cycle is impossible WebClausius inequality was given for a thermodynamic cycle. It can be extended into the noncyclic process of a closed thermodynamic system. In the case of the first law of …

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 inequality of Clausius is a corollaryof the second law of thermodynamics. It will be demonstrated to be valid for all possible cycles, including both reversible and irreversible heat engines and refrigerators.

WebMar 5, 2024 · Clausius’ theorem. The cyclic integral of ∂Q/T for a reversible cycle is always equal to zero. Let’s consider a reversible heat engine. From the absolute thermodynamic scale of temperature, we know that for a reversible process. ∫CYCLE (∂QR/T) = 0 …. (1) Hence proved that the cyclic integral of ∂Q/T for a reversible cycle is ... The Clausius theorem (1855), also known as the Clausius inequality, states that for a thermodynamic system (e.g. heat engine or heat pump) exchanging heat with external thermal reservoirs and undergoing a thermodynamic cycle, the following inequality holds. where is the total entropy change in the external thermal reservoirs (surroundin…
