As per Gilliland's equation, the diffusivity is___________________?
Correct answer: D. All A , B. & C.
- A. Directly proportional to 'T1.5'
- B. Inversely proportional to 'P'
- C. Dependent on the molecular volume & molecular weight of components
- D. All A , B. & C.
Explanation
Gilliland's diffusivity correlation gives diffusivity proportional to T^1.5 and inversely proportional to pressure, while also including molecular weight and molecular-volume terms. Therefore all three listed dependencies apply.
