WebA cyclical process brings a system, such as the gas in a cylinder, back to its original state at the end of every cycle. All heat engines use cyclical processes. Heat engines do work by using part of the energy transferred by heat from some source. As shown in Figure 12.14, ... WebSadi Carnot introduced the Carnot cycle in an analysis of the efficiency of heat engines in the early 19th century. He showed that efficiency was lost whenever heat engines deviated from being in thermal equilibrium and that any heat engine operating between a maximum temperature, T1, and a minimum temperature, T2, could not have greater efficiency than a …

WebYour first equation is correct, but your second one isn't. For the Carnot engine, the equation for efficiency with respect to temperature is [eff = 1+ (Tc/Th)]. To get the efficiency of a Carnot refrigerator, you would have to start from your first equation [eff = (Qc/W)], substitute W with (Qh-Qc), and then do the same procedure as Sal where ...
