UmeshMathur,
Yes, I want to back-calculate. When the pressure drop is given, I want to calculate the mass rate. In addition to pressure drop, there could be several other properties availible, but I was looking for general correlations. It would also be helpful to investigate the sizing...
I'm trying to review litterature in how to estimate rates in control valves under two-phase flow conditions. My application will be in petroleum, so there is chance of mass transfer between the two phases.
I've found some relevant litterature written for sizing and calculation of relief...
