If an automobile engine burns petrol at a temperature of `816^(@)C` and if surrounding temperature is `21^(@)C` ,what is its maximum percentage ?

Text Solution

Verified by Experts

% Efficiency - `[(T_h-T_c)/T_h]xx100`
Here
`T_h`=816+273=1089 K , `T_c`=21+273=294 K
% Efficiency =`((1089-294)/1089)xx100`
% Efficiency =73%
