Limitations of the Carnot cycle for?
The Carnot Heat Engine Cycle and the Carnot Heat Pump Cycle are reversible cycles and do not exist in any actual operation. However, they are very useful for predicting maximum possible thermal efficiencies and coefficients of performance using the absolute temperature of the heat source and the absolute temperature of the heat sink. The Carnot Cycle consists of two reversible and adiabatic ( isentropic ) steps and two reversible and isothermal steps.
What is reversible and irreversible process?
Very simple The Reversible Process: That type of process that work cycle, it mean to complete revolution and come back to the initial point from where it start. Example are Carnot Cycle. Two and Four stroke engine. Irreversible Process: Opposite to reversible process called irreversible process. Example are Electricity
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 is the COP of the reversed Carnot cycle for refrigeration?
COP will be the quocient between what you want over what you payed for that is: QC / WC Or for a reversible carnot cycle since WC = QH-QC QC / (QH-QC) or TC / (TH - TC) Where TC - Temperature of the cold reservoir TH - Temperature of the hot reservoir WC - Work of compression QH - Heat given to the hot reservoir QC - Heat taken from the cold reservoir
What do you mean by carnot cycle?
carnot 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

What are examples of isothermal process?
An isothermal process is a change in a system where the temperature stays constant (delta T =0). A practical example of this is some heat engines which work on the basis of the carnot cycle. The carnot cycle works on the basis of isothermal.
Is the volume expanded and the volume compressed during carnot cycle is equal?
Since it is a CYCLE, the overall volume change from minimum volume to maximum volume and back must sum to zero, thus the volume expanded must equal the volume compressed. Now, bear in mind that the Carnot Cycle consists of 4 steps:Reversible isothermal expansion of the gas at the "hot" temperature, T1 (isothermal heat addition or absorption).Isentropic (reversible adiabatic) expansion of the gas (isentropic work output).Reversible isothermal compression of the gas at the "cold" temperature, T2. (isothermal heat rejection)Isentropic compression of the gas (isentropic work input).Although when you graph the cycle on a PV diagram, it looks pretty similar, there is no requirement that the volume change in step 1 matches the volume change in step 3, nor that the volume change in step 2 match that in step 4.
Name 2 pairs of reversible reations that can occur in the water cycle?
Evaporation and condensation are reversible reactions. They occur in water 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.
Why carnot cycle are consider as ideal reversible cycle?
carnot cycle is the highiest efficiency
Why carnot cycle is called a two adiabatic and two isothermal process?
Adiabatic means there's no heat transference during the process; Isothermal means the process occurs at constant temperature. The compression and expansion processes are adiabatic, whereas the heat transfer from the hot reservoir and to the cold reservoir are isothermal. Those are the two adiabatic and isothermal processes.
What does a sudden burst of cycle tire represent the opsions are 1.isothermal 2.isobaric 3.adiabatic?
adiabatic
What is first order cycle reversible reaction?
A 4carbon compound
What 2 processes make water cycle?
Evaporation , condensation makes water cycle. These are reversible processes.
What is carnot engine in thermodynamics?
A Carnot cycle representes a gas undergoing a theoretical - means it cannot be implemented realistically - thermodynamic cycle composed of 4 reversible steps (meaning you can go back and everything will be back to the state it was, or scientifically speaking, the entropy of the universe will remain constant): 1- isothermal expansion of the gas (working fluid) - heat is added from the surroundings to the working fuild and it expands at constant temperature; 2- isentropic expansion of the gas - the gas is allowed to expand and produce work; 3- isothermal compression of the gas - the gas rejects heat to the surroundings at constant temperature; 4- isentropic compression of the gas - the gas is compressed and work is need for that compression.
