Weight calculations are an
important factor when
designing, repairing
cylinders or transporting a
piece. To calculate an
accurate weight you need to
know the volume of the bar
and the density of the
material in cubic inches.
To calculate the volume of a
round bar:
Divide Pi by 4. This
will always equal
0.7854. Multiply 0.7854
times the Diameter
Squared times the Length
in inches. This will
give you the cubic
inches or volume of the
bar being calculated.
(p
/ 4) x D2 x L =
Volume of the Bar
or 0.7854x D2
x L = Volume of the Bar
p
= Pi or 3.14159
D = Diameter L = Length in
inches
(p
/ 4) = 0.7854
Example we have a 6.000" bar
x 120" in length
0.7854 x 6.000 x 6.000 x
120" = 3,392.928 Cubic
inches
Once you know the cubic
inches or volume of the
bar you can calculate
weight by multiplying
the density of the
material times the
volume to get the weight
of the piece.
Now if we know the
density of the material
we can calculate the
weight. 3,392.928 x
density = Weight per
piece
6061 Aluminum has a
density of 0.098 or
332.51 lbs
Titanium has a density
of 0.1630 or 553.05 lbs
Ductile Iron has a
density of 0.255 or
865.20 lbs
1045/4340/8620 has
density of 0.2840 or
963.59 lbs
304 SS has a density of
0.2890 or 980.56 lbs
660 Bearing Bronze has a
density of 0.3180 or
1,078.95 lbs
Gold has a density of
0.6970 or 2,364.87 lbs
Another popular formula
for calculating weight
on carbon steel
1045/1050 CPO/IHC bars
is: D2 x 2.67
= Weight per Foot
