Question

Two heat engines operating between temperatures 2000 K and T K, T K and 500 K respectively. What is the intermediate temperature, if the efficiency of both the cycles is same?

दो ताप इंजन क्रमशः 2000 K और T K, T K और 500 K तापमान के बीच चल रहे हैं। यदि दोनों चक्रों की दक्षता समान है तो मध्यवर्ती तापमान क्या है?

A.

900 K

B.

1000 K

C.

1500 K

D.

1600 K

Answer ( Option B)

1000 K

Solution

Given :

 Maximum temperature (T1) = 2000K

Minimum temperature (T3) = 500K

Intermediate temperature = T K

According to question,

..Method 2...

Hence, the correct option is (B).
