Converting Nox mass fraction to ppm

    • ArunKumar108

      Hello Everyone,

      I need some clarification on the formula used in Ansys guideline to convert NOx mass fraction to ppm in the results section. While I was searching on how to convert Nox to ppm I recently came across the Ansys Guideline wherein some formula has been used to convert Nox in mass fraction to ppm. But I don't understand the formula there is no proper reference or detail description of how this formula has been derived.

      It would be a great help if people can throw some insights and maybe some reference to this formula with an explanation.

      I have attached the screenshot from the Ansys guideline. Perhaps it can help you people in answering.
