How to use the application

  • Beggs and Brill Compressibility equation is applied
  • Enter valid pressure value in psig
  • Enter valid temprature value in deg F
  • Enter valid specific gravity value
  • Enter valid mol %age values of CO2, N2 and H2S. Enter '0' if not present in the mix gas
  • Press 'Calculate' button then application will calculate gas compressibility, density and viscosity in results
  • Press 'Example' button to reset to default inputs and learn how inputs should be provided
  • Application will also calculate pseudocritical pressure and temperature values
  • There are various other techniques and procedures to calculate gas properties
  • For more extended features and options please review the application available on the site
