Dimensionless Groups

 

This spreadsheet will calculate dimensionless groups that commonly appear in non-isothermal, reacting gas flows. Some properties depend on temperature, pressure, and composition, while others also depend on length and velocity scales characteristic of the system under study.

 

  Temperature:

  (Required)
  Pressure:

  (Required)

  Length scale:

  (Optional) 

  Velocity scale:

  (Optional) 

You can enter
a velocity, or
a flow rate
and diameter
or area, and
the velocity
will be
computed.

or  

  Flow Rate (STP):

 
 

and

 
  Conduit/pipe
diameter:

 
 

or

  Cross sectional
area for flow:

 

 

Currently, at least two species must be specified. If one species is present in excess, such as a bath gas or diluent, list it first.
