how to calculate a tube theoretic weight
T.W.=(D-S)*S*24.65/1000
T.W.=(A-S)*S*31.4/1000
T.W.=((B+A)/2-S)*S*31.4)/1000
T.W.=[(24.65*(B-S))+(15.7*(A-B))*S]/1000
T.W.=12.33*(B+A-2S)*S/1000
T.W.=[(A+(B/2*3.14))/2/2-S]*S*3.14
Remark:
the unit in the formula:
length: meter
area: square meter
others: millimeter
weight:kgs
T.W.=24.65*(1.1*SW+1.2*S)*S/1000
T.W.=24.65*(1.06*SW+1.11*S)*S/1000
