Cal é o peso teórico dun tubo de aceiro
Se o diámetro exterior e o peso están en milímetros:
Peso por pé (lb/ft)=(OD−WT)×WT×0,01657
Se o diámetro exterior (OD) e o grosor da parede (WT) están en polgadas:
Peso por pé (lb/ft)=(OD−WT)×WT×10,69
O pé (símbolo: ft) é unha unidade de lonxitude no sistema imperial.
Singular: 1 pé (1 ft). 1 pé ≈ 0,3048 metros
Plural: 2 pés (2 ft). O símbolo "ft" permanece inalterado na forma plural.
Como calcular o peso dun tubo Sch 40 de 6 polgadas
Sch40 de 6 polgadas: diámetro exterior 168,3 mm e peso 7,11 mm:
Peso por pé (lb/ft)=(168,3−7,11)×7,11×0,01657 = 18,99 lb/ft
Peso por m² (kg/m²)=(168,3−7,11)×7,11×0,0246615 = 28,26 kg/m²
