Strength of glass

[silicabello]

Im trying to find exact information on the pressure allowed of borosilicate, preferably grams or lbs per mm.

I found this document on tensile strength...but yea I really dont understand its terminology

Anyone know?

13790t
p= -------
d

p = maximum working pressure in KN/M squared
t = wall thickness in mm
d = outside diameter in mm

100KN/M squared = 1 bar pressure

post didn't come out correctly.

p = 13790 x t, divided by d.

thanks raul!

I have an excel program that will figure out the internal pressure with ID and OD. I also have pdf file that has the pressure in a graph using ID and OD. I tried to post here, but couldn't upload a pdf file or excel file (at least I don't know how to do it). Send me a pm and I can email if you still need this....
