V= 529+tgy-ur/gay. = steel
kilo/ tonnes
375 pounds
weight of all steel can be calculated by multiplying unit volume with density.
20 MM
7.9kg/sq.M
8.913 Kg/m
DxD/162 this is the formula for finding unit weight of steel
If it section is a rolled like beam,channel,square,angles&flat. weight=Length x unit weight unit weight of this section is=123kg/m^3 If it is plate or sheet weight=Length x width x thickness x 7.85(sp.gravity of steel)
6.568 kg/m
16mm dia weight for running feet
No set answer to that, as steel pipes come in various diameters and wall thicknesses. If you want to be real accurate, they also come in various steel alloys, which do have some difference in density between them.
23.55 Kg.
