How to Calculate Prandtl Number?
Prandtl Number calculator uses Prandtl Number = Specific Heat Capacity*Dynamic Viscosity/Thermal Conductivity to calculate the Prandtl Number, The Prandtl number (Pr) or Prandtl group is a dimensionless number, named after the German physicist Ludwig Prandtl, defined as the ratio of momentum diffusivity to thermal diffusivity. The Prandtl number is often found in property tables alongside other properties such as viscosity and thermal conductivity.
For most gases over a wide range of temperature and pressure, Pr is approximately constant. Therefore, it can be used to determine the thermal conductivity of gases at high temperatures, where it is difficult to measure experimentally due to the formation of convection currents. Prandtl Number is denoted by Pr symbol.
How to calculate Prandtl Number using this online calculator? To use this online calculator for Prandtl Number, enter Specific Heat Capacity (c), Dynamic Viscosity (μ_{viscosity}) & Thermal Conductivity (k) and hit the calculate button. Here is how the Prandtl Number calculation can be explained with given input values -> 142.256 = 4184*1.02/6000.
