Difference between Carnot and ideal cycle?
What is the difference between ideal and actual cycle?
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.
Explain the reverse carnot cycle and from them go to ac?
Carnot Cycle is an ideal thermodynamic cycle that describes the functioning of a perfect heat engine. In the refrigeration system we need a cooling effect. So, in effect, refrigeration cycle is reverse in process than that of a carnot cycle, and ofcourse not ideal. Air-conditioners also run on the similar cycle as refrigerators.
Which cycle is best in heat engine?
The ideal cycle for a heat engine is often considered to be the Carnot cycle, as it provides the maximum possible efficiency between two temperature reservoirs. This theoretical cycle operates through four reversible processes: two isothermal and two adiabatic. Although real engines cannot achieve Carnot efficiency due to practical limitations and irreversibilities, the Carnot cycle serves as a benchmark for evaluating the performance of actual heat engines. Other cycles, like the Otto or Diesel cycles, are commonly used in practice, but they are less efficient than the Carnot cycle.
What is reversibility in thermodynamics?
Ideal Carnot Cycle is one example It is a process that does not have an energy loss.
Why is carnot cycle not suitable as an ideal cycle for all power producing cyclic devices?
The Carnot Cycle is a prime example of what is possible under the laws of physics however the cycle is impractical to build. The facts that its keeps stepping back and forth from isothermal to adibatic processes make it very hard to construct.
What did Sadi Carnot invent?
He invented the idea of the ideal thermodynamic cycle.
What is the difference between the Carnot cycle and the Rankine Cycle?
carnot cycle is a very ideal cycle that isn't practical at all , 'cause we add and reject heat isothermally , a wet mixture enters the turbine so it'll cause pitting and erosion and a wet mixture enters the pump , and the pump can't deal with a 2 phases fluid rankine cycle is a practical cycle but with a very low efficiency so the main difference lies in the adding and rejecting of heat
What factors reduce the efficiency of heat engine from its ideal value?
This inefficiency can be attributed to three causes. There is an overall theoretical limit to the efficiency of any heat engine due to temperature, called the Carnot efficiency. Second, specific types of engines have lower limits on their efficiency due to the inherent irreversibility of the engine cycle they use. Thirdly, the non ideal behaviour of real engines, such as mechanical friction and losses in the combustion process causes further efficiency losses.OR· friction of moving parts· inefficient combustion· heat loss from the combustion chamber· departure of the working fluid from the thermodynamic properties of an ideal gas· aerodynamic drag of air moving through the engine· energy used by auxiliary equipment like oil and water pumps· inefficient compressors and turbines· imperfect valve timing
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
What is the advantage of Otto cycle?
The Otto cycle, which is the ideal cycle for gasoline engines, offers several advantages, including higher thermal efficiency compared to simpler cycles like the Carnot cycle. Its design allows for a more compact engine size and lighter weight, making it suitable for automotive applications. Additionally, the cycle's ability to operate at a higher compression ratio contributes to improved fuel economy and reduced emissions. Overall, the Otto cycle balances performance and efficiency, making it a popular choice in internal combustion engines.
What is a real practical cycle based on ideal theoretical cycle?
