Carbon dioxide - Prandtl Number vs. Temperature and Pressure
The Prandtl Number - Pr - is a dimensionless number approximating the ratio of momentum diffusivity (kinematic viscosity) to thermal diffusivity - and is often used in heat transfer and free and forced convection calculations.
The Prandtl number can for calculations be expressed as
Pr = μ Cp / k (1)
where
μ = absolute or dynamic viscosity (kg/m s, lbm/(ft h))
Cp = specific heat (J/kg K, Btu/lbmoF)
k = thermal conductivity (W/m K, Btu/(h ft2oF/ft))
Below, Prandtl numbers for carbon dioxide at varying temperatures and pressures are given in figures and table.
