Weights of Tufnol Laminated rods and tubes
Calculate the approximate weight of Tufnol rods as follows:
Calculate weight in kg:
D = diameter in mm
L = length in metres
G = specific gravity for grade (see above)
Weight in kg = 0.007854 x D2 x L x G
Calculate the approximate weight of Tufnol tubes as follows:
Calculate weight in kg.
D = Outside diameter in mm
d = inside diameter in mm
L = length in metres
G = specific gravity for grade (see above)
Weight in kg = 0.007854 x (D2 – d2) x L x G
