Enter the specific heat capacity, dynamic viscosity, and thermal conductivity into the calculator to determine the prandtl number.
Prandtl Number Formula
The following formula is used to calculate the prandtl number of a system.
P = n * Cp / Tc
- Where P is the prandtl number
- n is the dynamic viscosity (kg*m^-1*s^-1)
- Cp is the specific heat capacity (J*kg^-1*K^-1)
- Tc is the thermal conductivity (W*m^-1*K^-1)
Prandtl Number Definition
A prandtl number is a ratio of the momentum of diffusivity to thermal diffusivity.
