Prandtl number is given by__________________?
Correct answer: C. CP μ/k
- A. CP μ/a
- B. hD/k
- C. CP μ/k
- D. μ/h CP
Explanation
Using thermal diffusivity α = k/(ρCp) and momentum diffusivity ν = μ/ρ gives Pr = ν/α = μCp/k. Thus the heat-capacity term must multiply viscosity and be divided by thermal conductivity.
