What is the Carnot cycle efficiency formula?
What is the Carnot cycle efficiency formula?
The ideal Rankine cycle efficiency (or Carnot cycle efficiency) can be defined as (T2-T1)/T2. T2 is defined as the absolute temperature of the heat source and T1 is the absolute temperature of the heat sink.
What is Carnot cycle in thermodynamics?
: an ideal reversible closed thermodynamic cycle in which the working substance goes through the four successive operations of isothermal expansion to a desired point, adiabatic expansion to a desired point, isothermal compression, and adiabatic compression back to its initial state.
What is the working fluid of Carnot cycle?
Explanation: In a carnot cycle the working medium receives heat at a higher temperature and rejects heat at a lower temperature. 3. In a carnot cycle, what is the working fluid? Explanation: As Carnot cycle is an ideal cycle, so the working fluid is an ideal gas.
How do you calculate work done by a heat engine?
The useful work done by a heat engine is W = Q1 – Q2 (energy conservation). An ideal reversible engine does the maximum amount of work.
What is the working principle of a Carnot cycle?
In a Carnot cycle, the working substance is subjected to a cyclic operation consisting of two isothermal and two adiabatic processes. The engine developed by Carnot has air (which is assumed to work as a perfect gas) as its working substance enclosed in a cylinder, in which a frictionless piston A moves.
What is Carnot cycle and its efficiency?
The Carnot cycle is a theoretical ideal thermodynamic cycle proposed by French physicist Nicolas Léonard Sadi Carnot in 1824 and expanded upon by others over the next few decades. It provides an upper limit on the efficiency that any classical thermodynamic engine can achieve during the conversion of heat into work, or conversely, the efficiency of a refrigeration system in creating a temperature difference by the application of work to the system. It is not an actual thermodynamic cycle but is
Why do we use the Carnot cycle?
The Carnot cycle is the most efficient possible engine, not only because of the (trivial) absence of friction and other incidental wasteful processes; the main reason is that it assumes no conduction of heat between parts of the engine at different temperatures.
What is the difference between Carnot cycle and Rankine cycle?
• Carnot cycle is a theoretical cycle whereas the Rankine cycle is a practical one. • Carnot cycle ensures the maximum efficiency under ideal conditions, but the Rankine cycle ensures the operation in real conditions.
