FLUIDAT® on the Net

Welcome to FLUIDAT® on the Net

FLUIDAT is a collection of routines to calculate physical properties of gases and liquids. These routines are made available at the FLUIDAT on the Net website.

Physical properties

This program is not neccessarily for users of Bronkhorst Mass Flow Meters and Controllers. Physical properties of liquids and gases that can be calculated are:

  • Density
  • Viscosity, both kinematic and dynamic
  • Specific heat at constant pressure (Cp) and constant volume (Cv)
  • Thermal conductivity
  • Boiling point
  • Vapor pressure curves
  • Molecular mass
  • Heat of vaporisation

Flow Calculations

This program offers the possibility to make a number of calculations related to Bronkhorst Mass Flow Meters and Controllers, for example the calculation of

  • Kv-values and orifice diameters for control valves
  • Pressure loss over partical filters for gases and gas mixtures

Some additional calculations are being prepared and will be released as soon as possible, e.g. conversion factor calculations for gases and for liquids.
