Transcribed Image Text:A Carnot engine whose sink is at 300 K has an efficiency of 40%. By how much should the
temperature of source be increased so as to increase its efficiency by 50% of original efficiency?
Expert Solution
Step 1
As given in the question,
Temperature of sink = TL = 300 K
Initial efficiency of Carnot engine = η1 = 40 % = 0.4
New efficiency of Carnot engine = η2 = Original efficiency + 50 % of original efficiency = 0.4 + (50% of 0.4) = 0.6
Let us take,
Initial temperature of source = TH1
New temperature of source = TH2
