You need to use the last formula to find out the equivalent surface area. Then, you just plug it back into the original equation //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

round port is radius x 2 x 3.14 x length / 1728 for displacement right?

Almost, radius^2 x 3.14 x length /1728.

No, I'm fully aware that gorilla glue works well, but it's a classic jack of all trades, but a master of none. It expands annoyingly and gets everywhere. If you have a proper cut joint, or even some silicone, then you shouldn't need expanding glue. Also, wood glue is chemically superior for wood only, and it's about over 1/2 as expensive.

You didnt read what I said very well. I wasnt saying Gorilla Glue makes a better box. Woodglue holds up fine. I said it soaks in deeper and makes a stronger bond, whether it be physical or chemical. I can bolt two pieces of metal togather or I can weld two pieces of metal togather. The welded one wont nessicarily be stronger. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

And trust me, when you brake apart a box made with gorilla glue or Resin the MDF will tear MUCH deeper than braking a box apart made with woodglue.

in the light of things, i prefer woodglue (tb 2) as it cleans up so quickly with a wet towel.

I don't agree because I've done panel testing on basically every glue suitable for box building that is available at your local hardware store. Woodglue was years ahead of gorilla glue, the bond just kinda sheared off with the gorilla, while I snapped the panel glued with titebond. Liquid nails was worse than both of them, and the elmer's polyurethane glues were the worst of all.

I would be interested to try the Loc-tite wood glue out... their spray glue sucks, but maybe the wood glue is OK //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

I havent done controll testing but here is what I've seen.

WoodGlue: When the corners are broken the MDF brakes or a few layres tare off, depending on how it was broken apart.

Gorilla Glue: When the corners are broke apart the MDF usually brakes, if it tares if tares DEEP

Polyester Resin (what you use to fiberglass and coat the inside of boxes with): It tore DEEP like with Gorilla glue but the tares where uneven and blotchy, they alternated between the two sides of the joint.

Liquid Nails: A joke of an adheasive for box building at best. Just Screws where stronger by far.

Titebond II: MDF broke or tore the top few layres off, similar to woodglue.

Thoes are the only adheasives I've tried. Agian, woodglue works fine. I just saw that gorilla glue and polyester resin soaked in deeper and held stronger.

titebond is wood glue //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Titebond 2 is a good glue, and probably the best value for money as well.
