Erosional Velocity in Nozzels
Erosional Velocity in Nozzels
(OP)
I have to calculate erosional velocity through an inlet nozzel of a flare knock out drum. I am not sure if it has to be calculated the same way as we calculate for the pipelines. Can someone give me some tips/ or reference where i can find the related information.
thanks
thanks

The TEMA code (for shell-and-tube heat exchangers)has limitations on fluid momentum which affects nozzle sizes. When the momentum criteria is exceeded, TEMA requires impingement plates on tube bundles.
You typically end up with a limit of 3-5 ft/second for the fluid.
Although this does not specifically apply to your vessel, it is reasonable to argue that if you conditions meet the TEMA criteria, they should be acceptable for your case.
My opinion only ..
