The Prandtl number of a fluid is the ratio of
- Athermal diffusivity to momentum diffusivity
- momentum diffusivity to thermal diffusivity
- Cconductive resistance to convective resistance
- Dthermal diffusivity to kinematic viscosity
Explanation
Pr=ν/α, the ratio of momentum diffusivity (kinematic viscosity) to thermal diffusivity.
