Prandtl Number
A dimensionless group often used in heat exchange calculations, relating the ratio of a fluid′s capacity to diffuse momentum to its capacity to diffuse heat.
- where
- P = Prandtl Number
- Cp = specific heat capacity [Jkg-1K-1]
- η = dynamic viscosity [kgm-1s-1]
- λ = thermal conductivity [Wm-1K-1]
- Cp = specific heat capacity [Jkg-1K-1]
