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.

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.


What is the significance of the Carnot COP in the efficiency of heat engines?

The Carnot COP is significant in the efficiency of heat engines because it represents the maximum possible efficiency that a heat engine can achieve. It serves as a benchmark for comparing the performance of real-world heat engines, helping engineers to design more efficient systems.

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 the carnot's heat engine has more efficiency than the heat engine?

The Carnot's heat engine is an ideal heat engine.In this process the source has infinite thermal heat capacity and the temperature of the source is constant( when we take large amount of heat from the source but it has same temperature ) .This is one assumption. The sink is also this condition means if it gain maximum heat energy from the source the temperature of the sink is also constant . this is another assumption. Ideal gas works as working substance(system).enclose in a cylinder whose walls and piston are perfectly adiabatic and base is perfectly diathermic.conversion of heat to work is an irriversible process but in carnot's heat engine it is possible.the initial temparature of system is infinite it is depend on temparature of the system.the perfect ideal gas and the perfect insulators are not exist so this process is only assumption.there is no heat engine which has more efficiency than the carnot's heat engineRGUKT IIIT NUZVID: N091528http://wiki.answers.com/'Why_is_the_carnot_efficency_the_maximum_efficiency_for_a_heat_engine&action=edit

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.

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.

What is the carnot statement of the second law of thermodynamics?

The efficiency of a quasi-static or reversible Carnot cycle depends only on the temperatures of the two heat reservoirs, and is the same, whatever the working substance. A Carnot engine operated in this way is the most efficient possible heat engine using those two temperatures
