I would like to ask for advice

I would like to ask the experts: when calculating the discharge volume of a safety valve, if the discharged medium is a mixture of gas and liquid phases, which one should be used as the basis for calculation?
It’s hard to calculate. If the pipeline or container contains a liquid and vaporization occurs during discharge, resulting in a two-phase flow of liquid and vapor, then the amount of vaporization at the valve opening is around 10%. My humble suggestion: calculate a liquid discharge value to determine the throat diameter ； Then, the emissions in the gas phase/vapor phase within a container are calculated to determine a throat diameter. Then, choose one throat diameter between the two that is close to the liquid phase but larger than the liquid phase. Just trying to spark some discussion, guys – please don’t reject my idea.
