Analogy between mass and heat transfer is not applicable in case of____________________?
Correct answer: D. Both B. and C.
- A. Same velocity profile or equal eddy diffusivities
- B. Thermal or pressure mass diffusion
- C. Viscous heating or chemical reaction
- D. Both B. and C.
Explanation
Heat and mass-transfer analogies require comparable transport mechanisms and no additional effects such as thermal or pressure diffusion, viscous heating, or chemical reaction. Therefore both listed limitations apply.
