7 Feb 2005 No process is possible whose sole effect is transfer of heat from a colder to a hotter body. It was mentioned When we considered the Carnot cycle for an ideal gas we have found that efficiency of the cycle ? = (Th ? Tc)/Th depends only on temp. of two heat baths and does not depend of gas characteristics
Carnot proposed that a cycle comprised of completely (internally and externally) reversible processes would give the maximum amount of net work for a given heat input, since the work done by a system in a reversible (ideal) process is always greater than that in an irreversible. (real) process. THE CARNOT HEAT ENGINE
Thus, the efficiency of any process will always be less than 100%. - The third law of thermodynamics tells us that all molecular movement stops at a temperature we call absolute zero, or 0 Kelvin (-273oC). Since temperature is a measure of molecular movement, there can be no temperature lower than absolute zero.
13 Oct 2011 Carnot cycle - 2 when the fluid and the reservoir reach thermal equilibrium. That is, no more work can be produced when the temperature of the fluid becomes the same as that of the reservoir. To continue the process, the fluid must be made in contact with another reservoir with a different temperature.
A Carnot gas cycle operating in a given temperature range is shown in the T-s diagram in Fig. 4.1(a). One way to carry out the processes of this cycle is through the use of steady-state, steady-flow devices as shown in Fig. 4.1(b). The isentropic expansion process 2-3 and the isentropic compression process 4-1 can be
Efficiency of a Carnot engine. The Carnot cycle makes an engine. The p-V diagram below sketches the operation of a Carnot engine, where the “working fluid" that expands and contracts within the cylinder is an ideal gas. V p. 0. 0. TL. TH a b c d. 1. 2. 3. 4. Here the high temperature TH and the low temperature TL are
Reversible cycles such as Carnot cycle have the highest thermal efficiency of all heat engines operating between the same temperature levels. Unlike ideal cycles, they are totally reversible, and unsuitable as a realistic model. 5. Care should be exercised in the interpretation of the results from ideal cycles. On both P-v and
When a system is taken through a series of different states and finally returned to its initial state, a thermodynamic cycle is said to have occurred. In the process of going through this cycle, the system may perform work on its surroundings, thereby acting as a heat engine. A system undergoing a Carnot cycle is called a
A thermodynamic cycle consists of a series of thermodynamic processes transferring heat and work, while varying pressure, temperature, and .

After reaching maximum compression, the gas expands isothermally at temperature T. H . Heat Q. H. = Q. 34 is transferred into the gas. 4. The gas expands adiabatically, with Q = 0, until the temperature decreases back to T. C . Work is done in all four processes of the Carnot cycle, but heat is transferred only during the two
