### 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: Kelvin Celsius Rankine Fahrenheit (Required) Pressure: Torr atm Pa bar psi (Required) Length scale: cm inch ft mi km (Optional) Velocity scale: cm/s ft/s mph kph (Optional)  You can enter a velocity, or a flow rate and diameter or area, and the velocity will be computed. or Flow Rate (STP): slm sccm cfm cm^3/s m^3/s and Conduit/pipe diameter: cm inch ft mi km or Cross sectional area for flow: cm^2 inch^2 ft^2 m^2 mi^2 km^2
 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.
