Hey friends,

I have a 2 phases flow in a tube,
I need to calculate average velocity of each phase in a section,
I think it's better to determine function of mass flow distribution by tube radius [mdot(r)] first then by using V=mdot/A*ro and an integral average velocity could be calculated,

But I haven't any idea to calculate mdot through the radius,

Do you have any suggestion!? Or another way to calculation of average velocity...!?
