Enter the kinematic viscosity (m^2/s) and the mass diffusivity (m^2/s) into the Calculator. The calculator will evaluate the Schmidt Number. 

Schmidt Number Formula

Sc = v / Dc


  • Sc is the Schmidt Number ()
  • v is the kinematic viscosity (m^2/s)
  • Dc is the mass diffusivity (m^2/s)

To calculate the Schmidt Number, divide the kinematic viscosity by the mass diffusivity.

How to Calculate Schmidt Number?

The following steps outline how to calculate the Schmidt Number.

  1. First, determine the kinematic viscosity (m^2/s). 
  2. Next, determine the mass diffusivity (m^2/s). 
  3. Next, gather the formula from above = Sc = v / Dc.
  4. Finally, calculate the Schmidt Number.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

kinematic viscosity (m^2/s) = 200

mass diffusivity (m^2/s) = 1000
