Dear All,

 

I have calculated venting capacity as per API-2000 but could't found out the criteria for vent size calculation. Please give any reference or any other help iff possible.

 

Regards,

sunny,

 

The 3rd post of following link might be included a solution of your problem:

Sunny, Fallah is correct and I will add to what he has said.

 

Protego Vents (Germany) were very much involved in the development of the theory behind the latest API 2000 and I believe that they had written a paper describing the basis. This goes beyond calculating piping losses.

 

Let us know what ever you might find.

Being frankly, i have been searching TP-410 but could't so i finally decided to put the thread on forum.

Thanks Fallah for the same reference with formula's and thanks to Proinwv.

Can you please upload that technical paper.

By the way, i was just doing preliminary calculations as the project is in it's early stages so i used this criteria:

 

Velocity < 10 m/s

Maximum Pipe Length 10 m

Maximum pressure drop in piping 10 mmH2O

 

How about this criteria?

I do not have the paper. I suggest that you contact Protego.

 

Pressure drop is selected based upon the allowable backpressure and piping length need include the equivalent length of fittings and inlet/exit losses. Gas velocity affects the losses as well and generates noise at high velocities. This is a system, these factors interact.
