Quantum est pondus tubi ferrei per pedem?

Quod est pondus theoreticum tubi ferrei

Si OD et WT in millimetris sunt:

Pondus per pedem (lb/ft) = (OD−WT) × WT × 0.01657

Si Diameter Externus (OD) et Crassitudo Parietis (WT) in unciis sunt:

Pondus per pedem (lb/ft) = (OD−WT) × WT × 10.69

 

Pes (symbolum: ft) est unitas longitudinis in systemate imperiali.

Singularis: 1 pes (1 pes). 1 pes ≈ 0.3048 metra.

Pluralis: 2 pedes (2 ft). Symbolum "ft" in forma plurali immutatum manet.

Quomodo pondus tubi Sch 40 sex unciarum computare

Sch40 sex unciarum: diametro externo 168.3mm et pondere 7.11mm.

Pondus per pedem (lb/ft) = (168.3−7.11)×7.11×0.01657 = 18.99 lb/ft

Pondus per m² (kg/m²) = (168.3−7.11) × 7.11 × 0.0246615 = 28.26 kg/m²
