Engine cyccle useful work calculation

WebW = Qh −Qc. W = Q h − Q c. The most important measure of a heat engine is its efficiency (e), which is simply “what we get out” divided by “what we put in” during each cycle, as defined by e = W out/Qin. e = W out / Q in. With a heat engine working between two heat reservoirs, we get out W and put in Qh, Q h, so the efficiency of ... WebThe mean effective pressure (MEP) is a quantity relating to the operation of a reciprocating engine and is a measure of an engine's capacity to do work that is independent of engine displacement. When quoted as an indicated mean effective pressure (IMEP), it may be thought of as the average pressure acting on a piston during the different portions of its …
