I do not know but I can tell you the MAXIMUM efficiency which is that of a Carnot cycle
High temp = 680 + 273 = 953 Kelvin
Low Temp = 220 + 273 = 493 Kelvin
Carnot efficiency = 100*(hot-cold)/hot
= 100 (953-493)/953
= 48.3 %
A heat engine has a hot reservoir of 680°C and a cold reservoir of 220°C. What is the efficiency of the engine?
