ABSTRACT
The Carnot cycle was introduced in Chapter 2. The cycle 1-2-3-4-1, as depicted in Figure 2.6, is a Carnot cycle, and it is a power cycle as well. In Figure 2.6 we note that the state point moves in a clockwise sense in the p-V plane. The area enclosed by the two isothermal and two isentropic processes represents net positive work, or work done by the system on the surroundings. State point movement in the opposite sense is depicted in Figure 8.1 for a Carnot cycle on the T-S plane, but in this case the enclosed area represents negative net work, i.e., work which enters the system from the surroundings. The latter cycle is the so-called reversed Carnot cycle.
