How This Is Calculated


$$ Pr = \frac{\nu}{\alpha} $$ where:

Pr   =   Prandtl Numebr   (Dimensionless)

ν   =   Kinematic viscosity  (m²/s)

α   =   Thermal Diffusivity   (m²/s)


Assumptions


  • The fluid is incompressible.
  • The fluid flow is laminar.
  • The fluid is homogeneous.
  • Flow is single phase.
