Dear All, Basically, our client had their own standard drawing for self-supporting roof meeting EN 14015. Radio für mac kostenlos. However, the client decided to design this new tank as per API 650 which they don't have the standard drawing for the roofing structure.
Open Vent (Gooseneck) Sizing
Open Vent (Gooseneck) Sizing
Hi,
API 2000 does not mentioned anything about sizing selection for vent i.e. gooseneck. Thus, how do we decide on determine the size of the vent based on the calculated values (total inbreathing, total outbreathing, and emergency vent).
Say there is a problem where the inbreathing flowrate is the highest the rest and there is no need for emergency venting since the AST is design for frangible attachment. What are the deciding factors for calculating the size? I've also tried using Bernoulli equation to determine the velocity so I can use Q=Av formula to determine the vent pipe size however I don't it's right.
I also stumbled upon Morrison sizing selection and from that article / brochure there is something said about wetted area and vent size selection based on NFPA 30. I'm not sure that can be used or not so I seek experience from all user who have verse experience in determining the open vent size.
Thank you.
