velocity inlet: sparger
 

Is there a usual way to set the velocity of a gas sparger in a fluid. I imagine that the gas will decrease from the velocity in to the sparger system to the limit velocity of a bubble in a fluid

vlim2=4Dg.(rhol-rhog).g/3Cdrhog

But if you have a better way (with the pressure drop in the sparger system) you are welcome
