Default Superficial Reynolds number for two phase flow

Hi Fomers, I am trying to validate interFoam solver for two phase flow in a pipe, but had trouble calculating the velocities of 2 phases using the provided Reynolds number.

My test case is a pipe of 10mm diameter and 1.5m length. Re(liquid) = 6000 and Re(gas) = 832.

Can someone please provide your valuable suggestion on how I can find the velocity of 2 phases using the available Reynolds number?

I have attached the URL of the research paper and also the fluid properties.

The text gives superficial Re numbers.

The superficial value of Re is the one that each phase would have if the flow of that phase were flowing through the channel by itself.
