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.
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.
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 did the addition of a condenser improve the steam engine?
It increased the engine's efficiency, making it useful for other kinds of work.
What are the differene between stirling cycle and carnot cycle?
In Carnot & Stirling cycle there were 2 isothermal processes. but in Stirling engine other 2 processes are constant volume processes whereas in Carnot other 2 processes are isentropic processes. Stirling engine has low maintenance and easy to built because of there construction. Both cycle's efficiencies near to same. but operating according to there applications.
What is the Carnot engine problem and how does it relate to the efficiency of a heat engine?
The Carnot engine problem refers to the theoretical limit on the efficiency of heat engines, as described by the Carnot cycle. This problem highlights that no real heat engine can be 100 efficient, as some energy is always lost as heat. The efficiency of a heat engine is limited by the Carnot efficiency, which depends on the temperatures of the heat source and sink. This concept helps engineers understand and improve the efficiency of real-world heat engines.
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.
How to calculate the Carnot efficiency of a heat engine?
The Carnot efficiency of a heat engine can be calculated by dividing the temperature difference between the hot and cold reservoirs by the temperature of the hot reservoir. The formula is: Carnot efficiency 1 - (Tc/Th), where Tc is the temperature of the cold reservoir and Th is the temperature of the hot reservoir.
Is the energy of carnot engine is maximum?
The Carnot engine is the most efficient heat engine possible, but it does not produce maximum energy. It operates between two temperature reservoirs and has an upper limit on efficiency based on those temperatures. The efficiency of a Carnot engine is determined by the difference in temperature between the hot and cold reservoirs.
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
Why efficiency of carnot heat engine is 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.
What temperature would the cold reservoir need to be for a Carnot engine to achieve 100 percent efficiency?
For a Carnot engine to achieve 100 percent efficiency, the temperature of the cold reservoir would need to be absolute zero (0 Kelvin). This is because the efficiency of a Carnot engine is given by 1 - (Tc/Th), where Tc is the temperature of the cold reservoir and Th is the temperature of the hot reservoir, and efficiency is maximized as Tc approaches absolute zero.
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.
Which is the carnot engine formula?
carnot = carrot
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 the rate of heat output of a Carnot engine?
The rate of heat output of a Carnot engine depends on the temperature of the hot reservoir and the temperature of the cold reservoir. It can be calculated using the Carnot efficiency formula, which is the temperature difference between the hot and cold reservoir divided by the temperature of the hot reservoir.
Why carnot cycle are consider as ideal reversible cycle?
carnot cycle is the highiest efficiency
