Performance of Heat engine:

Performance of HP:  It is measured by thermal efficiency that is the degree of useful conversion of heat received into work.

 

 

η_th Net work output/ Total Heat supplied = W/Q₁  = (Q₁  - Q₂) / Q₁

η_th 1 -  Q2/Q1  =  1 -  T2/T1;       

As Q₁/Q₂ = T₁/T₂

Or,  Thermal  efficiency  can be  defined  as  ratio  of  net  work  gained(output) from system to heat supplied (input) to the system.
