The efficiency of the Carnot engine is 50 % and the temperature of the sink is 500 ~K . If the temperature of the source is kept constant and its efficiency raised to 60 % , then the required temperature of the sink will be:

Options

  1. A100 ~K
  2. B600 ~K
  3. C400 ~K
  4. D500 ~K

Correct answer

C. 400 ~K

Step-by-step solution

aligned & % = (1- T₂ T₁ ) 100 & For 50 %, 50 100 =1- 50 11 & T₁=1000 ~K & aim for 60 %, 60 100 =1- T₂ 1000 & T₂=400 ~K aligned
