SATHEE: Thermodynamics Question 161

Thermodynamics Question 161

Question: A carnot engine has the same efficiency between 800 K to 500 K and x K to 600 K. The value of x is

[Pb. PMT 1996; CPMT 1996]

Options:

A) 1000 K

B) 960 K

C) 846 K

D) 754 K

Show Answer

Answer:

Correct Answer: B

Solution:

In first case, $(η_{1}) = 1 - \frac{500}{800} = \frac{3}{8}$

and in second case, $(η_{2}) = 1 - \frac{600}{x}$

Since $η_{1} = η_{2},$

therefore $\frac{3}{8} = 1 - \frac{600}{x}$

or $\frac{600}{x} = 1 - \frac{3}{8} = \frac{5}{8}$ or $x = \frac{600 \times 8}{5} = 960 K$
