hello everyone.

so im not very bright. but i need to make some calculations anyway.

lets say i need to know the weight of 3.28ft (1meter) tube, and the only values that i have are specific weight/gravity and wall thickness ,

thanks for any help

p.s
anyone know the specific weight of 304 and 321.

 

you only need to look up the density of the material.
use matweb.com, wikipedia.org, or google.

if you do only have the sp. wt. then divide it by gravity, as the sp.wt=gravity*density
so youd most likely divide by 9.81 m/s^2 to get something in the units of kg/m^3


then multiply the volume of the tube.
vol=pi*[(od/2)^2-(id/2)^2]*length

------------------------------------------
specific gravity is a ratio of the density of your material divided by the density of water.
for you, multiply the value of your materials specific gravity (unitless) by 1000 kg/m^3 and youll have your material's density. then follow instructions above.

 

what he said!^^^^^^^

 

good post lol
