WebAnswer (1 of 4): In simple words ,Carnot engine is a theoretical and hypothetical engine which lives u maximum amount of work with the same input with respect to any engine. … WebFig. 9.6 depicts a model of combined Carnot engine and an isothermal combustor, which is often used in some arguments to justify that the upper limit of the fuel cell efficiency is the Carnot efficiency. Hydrogen and oxygen are fed to the combustor at temperature T C, and water exiting the combustor is discharged to the surrounding.The model of Fig. 9.6 is very …
A Carnot heat engine is a heat engine that operates on the Carnot cycle. The basic model for this engine was developed by Nicolas Léonard Sadi Carnot in 1824. The Carnot engine model was graphically expanded by Benoît Paul Émile Clapeyron in 1834 and mathematically explored by Rudolf Clausius in 1857, work that led to the fundamental thermodynamic concept of entropy. The Carnot engine is the most efficient heat engine which is theoretically possible. The efficiency dep… WebCarnot Cycle. The most efficient heat engine cycle is the Carnot cycle, consisting of two isothermal processes and two adiabatic processes. The Carnot cycle can be thought of as the most efficient heat engine cycle allowed by physical laws. When the second law of thermodynamics states that not all the supplied heat in a heat engine can be used ...
WebSep 10, 2024 · In 1st case, Carnot engine operates between temperatures 300 K and 100 K. In 2nd case, as shown in the figure, a combination of two engines is used. The efficiency of this combination (in 2nd case) will be : (A) same as the 1st case. (B) always greater than … WebThe Carnot engine cycle when acting as a heat engine consists of the following steps: Reversible isothermal expansion of the gas at the “hot” temperature. Isentropic (reversible adiabatic) expansion of the gas. …
WebApr 7, 2024 · A Carnot engine uses first an ideal monoatomic gas (γ = 5/3) and then ideal diatomic gas (γ = 7/5) as its working substance. The source and sink temperature are 41 1 ∘ C and 6 9 ∘ C respectively and the engine extract 1000 J of heat from the source in each cycle. Then : The efficiencies of the engine in the two cases are in the ratio 21: 25; The …
