1.	27. The efficiency of a Carnot engine betwe HTR at T, and LTR at T2 is given by:a) 1T1 -T.b) T-TITTTI-TTd)Ti-T2.T
Answer» not engine-η(efficiency)=1− T H T L T H = high TEMPERATURE (sources)T L = low temperature(SINK)For same efficiency, ratio of temperature should REMAIN same.Option (A)2T 1 and2T 2 2T 2 2T 1 = T 2 T 1
