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
the Carnot cycle has 2 constant specific volume processes (heat in & heat out) the air refrigeration cycle is based on a brayton cycle which has two constant pressure processes.
carnot cycle?
carnot cycle
Rankine cycle is used in steam turbine
ya it is practicaly imposible
Brayton cycle: It is open cycle. Rankine cycle: It's close cycle. Brayton cycle: Mostly used in gas turbine engine. Rankine cycle: Mostly used in power generation plant. Brayton cycle: Resemble less to Carnot cycle. Rankine cycle: Resemble is more to Carnot cycle.
What is the difference between ideal and actual cycle?
Rankine cycle allows for practical implementation with real working fluids such as water, making it more feasible for thermal power plants compared to the idealized Carnot cycle. Rankine cycle also allows for the use of turbines and pumps which are more efficient than isothermal expansion and compression processes in the Carnot cycle. Additionally, Rankine cycle can be modified with reheating and regeneration to improve efficiency further, something the Carnot cycle cannot achieve.
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.
the Carnot cycle has 2 constant specific volume processes (heat in & heat out) the air refrigeration cycle is based on a brayton cycle which has two constant pressure processes.
The Carnot cycle was proposed by Nicolas L©onard Sadi Carnot in 1823. It is a theoretical thermodynamic cycle. It is the most efficient cycle for creating a temperature difference.
carnot cycle?
carnot cycle is the highiest efficiency
reversible.But always remember that a carnot cycle is an idealized cycle and it is not
The Carnot cycle is a mathematical description of an engine that derives its power from heat.
no, a Carnot cycle is not practiclly possible.bcz carnot consist of two cycles. i.e 1-rev. adiabatic 2-isothermal
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.
