CARNOT CYCLE




Its an constant temperature process .there are in four process

  1. Two isentropic process
  2. two iso-thermal process 



Process (1-2):
§  It is an adiabatic reversible process.

§  In the process there is no heat rejected and added 

§  Volume decreases and pressure increases.

§  Temperature constant(T=C)
                                 


Process (2-3):
                          
§  It is an iso-thermal process.

§  In the process heat added 

§  Volume increases and pressure constant

§  Temperature decreases, entropy constant(s=c)

§  QS =(T3-T2)


Process (3-4):
§  It is an adiabatic reversible process.

§  In the process heat rejected 

§  Volume increases and pressure decreases.

§  Temperature constant
                         

Process (4-1):

                         
§  It is an iso-thermal process.

§  In the process heat rejected

§  Volume increases and pressure constant

§  Temperature increases, entropy constant(s=c)

§  Qr =(T4-T1)



Work done (w) =heat supplied (Qs)-heat rejected (Qr)

.                         = (T3-T2) = (T4-T1)

Efficiency of Carnot (ή) =work done /heat supplied

                                       = (T3-T2) -(T4-T1)/ (T3-T2)
