In a Carnot engine, the absolute temperature of the source is 25 % more than the absolute temperature of the sink. The efficiency of the engine is

Options

  1. A10 %
  2. B50 %
  3. C25 %
  4. D20 %

Correct answer

D. 20 %

Step-by-step solution

T ₂= T , ~T ₁=1.25 ~T Efficiency of cannot engine is =1- T₂ T₁ =1- T 1.25 T = 1 5 % = 1 5 100=20 %
