The dimension of diffusivity is same as that of the__________________?
Correct answer: C. Kinematic viscosity
- A. The dimension of diffusivity is same as that of the
- B. Density
- C. Kinematic viscosity
- D. Molal concentration
- E. Velocity head
Explanation
Molecular diffusivity has dimensions of length squared per time, such as m²/s. Kinematic viscosity has the same dimensions, although it describes momentum rather than mass transport.
