Hello everybody,
I want to calculate the pressure drop in a perforated pipe which is responsible for distributing a two phase flow in a stripping tower. The vapor volume flow rate is 68% of total flow rate. Perforated pipe diameter, the holes quantity and their diameter, vapor and liquid phase flow rates, their composition and density are known. Please let me know how can I calculate the pressure drop? (specially pressure drop through the holes) It would be appreciated, if anybody can introduce me any reference as well.

Sheyda,

 

I have some useful information about sizing and calculation of perforated pipes for liquid and gas but not both, I mean two phase fluid.

So, I am afraid of being applicable such data for your case.

Please let me know if you require my data.

Dear Mehdi,

In the case that I can find a two phase multiplier, it might be usefule. Please let me have the information.

Maybe you don't want to use a perforated pipe for this service. You probably should search for a more appropriate distributor, such as a vane.
