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 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… prostate shock wave therapy https://mainlinemech.com
