Why efficiency of carnot heat engine is always greater than that of an actual engine?

The efficiency of a Carnot engine is theoretically always greater than that of an actual engine. The fact that it is impossible to build a thermodynamically reversable engine, which is one of the variables necessary to calculate its superiority to a real heat engine, makes the theorum practical for assessing a real heat engines efficiency only.

Difference between Carnot and ideal cycle?
What is the difference between ideal and actual cycle?
Why you learn carnot cycle while it is not use in reality?
because it is the best theoretical engine. our aim is always to make our practical engine as close as that of carnot. if u don't know about the carnot cycle then how will u do that.
How can the efficiency of a Carnot Engine be increased?
Increase source temperature or decrease sink temperature.More efficient way is to decrease sink temperature.
Limitations of the Carnot cycle for the operation of the steam power plant?
The Carnot cycle gives the theoretical maximum efficiency of an engine operating between two heat reservoirs. The Carnot cycle is an idealized engine cycle that is thermodynamically reversible. Real systems such as power plants are not reversible, and the entropy of a real material changes with temperature (which is not accounted for by the Carnot cycle). A steam power plant operates closer to a cycle known as the Rankine cycle.
Carnot cycle is practically possible or not?
no, a Carnot cycle is not practiclly possible.bcz carnot consist of two cycles. i.e 1-rev. adiabatic 2-isothermal
Why carnot cycle are consider as ideal reversible cycle?
carnot cycle is the highiest efficiency
Does an ideal machine would have an efficiency greater than one?
No, an efficiency greater than one would not be possible, since that would violate a very fundamental law of physics: conservation of energy. The efficiency of an "ideal machine" would be one, in many cases; the efficiency of an ideal Carnot engine would be less than one.
Define the efficiency of carnot engine?
The efficiency of the carnot engine - or any engine for that matter - is given by the quocient between the desired effect and what you payed for it, that is, the quocient between the net work output and the heat added to the system.

Machine that transforms heat into mechanical energy?
A ficticious heat engine that works at the maximum theoretical efficiency is called a Carnot engine. Real engines, that obviously work at a lesser efficiency, include the combustion engines found in cars.A ficticious heat engine that works at the maximum theoretical efficiency is called a Carnot engine.

What is the coal energy efficiency?
If it is burned - which is the way such fuels are usually used - the energy efficiency is the energy efficiency of a heat engine. The theoretical maximum efficiency is the Carnot efficiency; the real efficiency will usually be considerably less than that.
What is a sample that has greater entropy?
A Carnot cycle is a sample of something that has greater entropy. The word entropy can e defined s meaning reverse system. The concept of entropy was started with the work of Lazare Carnot.
Is the energy of carnot engine is maximum?
The work output of a Carnot engine would be the maximum possible, i.e. it would yield the maximum possible efficiency for conversion of input energy into useful work.
Reversed carnot cycle assumes all processes in the cycle as?
reversible.But always remember that a carnot cycle is an idealized cycle and it is not
Which heat engine has more efficiency?
Carnot's heat engine has more efficiency then the other heat engine but it is assumption. Is is not real. RGUKT IIIT NUZVID: N091528
What is known as carnot heat engin?
carnot's heat heat engine is also known as ideal heat engine.because in carnot's the precess is reversible .Total heat converted into work . The efficiency is maximum for carnot's heat engine.
What is the efficiency of a carnot engine operating between boiling point and freezing point of water?
You must insert the temperatures, in Kelvin, into the formula. Freezing point of water: 273 K; boiling point of water: 373 K. Thus, you get a Carnot efficiency of (373 - 273) / 373, or about 27%.
