Air Jet Distance 3

[macmet]

Not sure this is in the right forum, I thought a few would be good for it.

But, does anyone know of a way to calculate the distance air/gas will move from the face of a nozzle based on air/gas velocity?

I have a fan that is exhausting air through a plenum, and I'd just like to know how far I can expect the air to "jet" out from the face of the plenum.

Any tips on where to look would be really appreciated. I've Googled it, and I'm not sure how confident I can be in what I've come across.

Cheers,

Macmet

Thanks for the link BigInch. Star for you.

Does anyone else have any other suggestions on where to look?

A JPEG attachment of a page copied from NSC 'Fundamentals of Industrial Hygiene" should help you. Also,I remember that Grainger had published graphs and data on air velocity at various distances from fan exhausts of fans they would sell,however, you had to make a special request for that information.

That is a great attachment Chicopee. Thanks very much.

Here is another JPEG attachment of a graph which is based on the manufacturer's data sheet.
