Many beginners with data knowledge may not be able to answer, but WTR will automatically add the default values for you. In extreme cases, you only need to enter 5 values: gas phase flow rate, gas phase density, liquid phase flow rate, liquid phase density, and liquid phase surface tension, and the calculation will be completed automatically!
