Carnot cycle: Action of a Carnot

Action of a Carnot cycle: The Carnot cycle shown in Fig. is a clockwise cycle. So the work done due to this cycle is positive and the area abcd of the cycle on the p-V diagram indicates this work (W). The two process b → c and d → a are adiabatic, i.e., in these two processes no heat exchange takes place with the surroundings. Again, the process a → b is an isothermal expansion. So the gas takes up heat Q 1 from the source at higher temperature T 1. On the other hand, the process c → ... The Carnot cycle – In 1824 Sadi Carnot proposed a theoretical heat engine to show that the efficiency was based upon the temperatures between which it operated. – Carnot’s imaginary engine could perform a series of operations between temperatures T1 and T2, so that at the end of these operations the system was restored to the original state. – This cycle of processes which occurred under reversible conditions is referred to as the Carnot cycle. – The medium employed in operating ... Carnot cycle ... A Carnot cycle is an ideal thermodynamic cycle proposed by French physicist Sadi Carnot in 1824 and expanded upon by others in the 1830s and 1840s. What is a Carnot Engine? The Carnot engine is a theoretical thermodynamic cycle proposed by Leonard Carnot. It estimates the maximum possible efficiency that a heat engine during the conversion process of heat into work and, conversely, working between two reservoirs can possess.
