Calculate the maximum % efficiency of thermal engine operating between `110^(@) and 25^(@)` .

Text Solution

Verified by Experts

% Efficiency =`[(T_1-T_2)/T_1]xx100`
`T_1=110^@C + 273`=383 K
`T_2=25^@C` + 273 +298 K
`therefore` % Efficiency =`[(383-298)/383]xx100`
`=(85xx100)/383=8500/383`
% Efficiency =22.2 %
