Cpμ/K is termed as the ______________ number?
Correct answer: C. Prandtl
- A. Grashoff
- B. Nusselt
- C. Prandtl
- D. Stanton
Explanation
The dimensionless group Cpμ/k compares momentum diffusivity with thermal diffusivity and is the Prandtl number. It indicates the relative thicknesses of velocity and thermal boundary layers.
