The formula to calculate the Prandtl Number (Pr) is:
\[ Pr = \frac{c \cdot \mu_{\text{viscosity}}}{k} \]
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.
Let's assume the following values:
Using the formula:
\[ Pr = \frac{4184 \cdot 1.02}{6000} \approx 0.71128 \]
The Prandtl Number is approximately 0.71128.
