Prandtl Number Calculator

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)


What is a Prandtl number?

The Prandtl number is a ratio of momentum diffusivity to thermal diffusivity.

What is momentum diffusivity?

Momentum diffusivity it the measure of a fluids resistance to movement. In other words, another way of say viscosity.
