WebW = QH - QL so efficiency = (QH – QL)/QH = 1 – QL/QH Since the engine is reversible in one complete cycle entropy will be same so we can use the first equation above and the … WebThe Kelvin-Planck and Clausius statements of thermodynamics are equivalent. In order to prove the equivalence, a heat-engine-refrigerator combined system is used as shown below. The system satisfies the following conditions, where QH and QL are known values. free mp3 trimmer app

Difference Between Air Conditioning and Refrigeration

WebHow can I differentiate between QH and QL in the refrigerator case in the second law of thermodynamics? Expert Answer 2nd law of thermodynamics tells us which processes in … WebAug 6, 2014 · The work accomplished us therefore the difference in the heat input and output (QH) - (QL), so the work accomplished represents the heat used, W = J(QH - QL) 83. … Webefficiency, and small memory QL is applicable to large-scale systems. Meanwhile, we present a novel reward setting, un-der which the optimal policy with minimal flipping actions to realize reachability is the one of the highest returns. Then, to obtain the optimal policy, we propose QL, and fast small-memory QL for large-scale systems. free mp3 transcription
