The value of Joule-Thomson co-efficient, in case where cooling occurs after the throttling process is________________?
Correct answer: D. +ve
- A. 0
- B. ∞
- C. -ve
- D. +ve
Explanation
During throttling, dT = μJT dP and the pressure change is negative. Cooling therefore requires μJT to be positive, so a positive coefficient gives a temperature drop across the valve.
