Jaká je teoretická hmotnost ocelové trubky?
Pokud jsou vnější průměr a šířka v milimetrech:
Hmotnost na stopu (lb/ft)=(vnější průměr − hmotnost)×hmotnost×0,01657
Pokud jsou vnější průměr (OD) a tloušťka stěny (WT) v palcích:
Hmotnost na stopu (lb/ft)=(vnější průměr − hmotnost)×hmotnost×10,69
Stopa (symbol: ft) je jednotka délky v imperiální soustavě.
Jednotné číslo: 1 stopa (1 stopa). 1 stopa ≈ 0,3048 metru
Množné číslo: 2 stopy (2 stopy). Symbol „ft“ zůstává v množném čísle nezměněn.
Jak vypočítat hmotnost 6palcové trubky sch 40
6 palců Sch40: vnější průměr 168,3 mm a hmotnost 7,11 mm:
Hmotnost na stopu (lb/ft)=(168,3−7,11)×7,11×0,01657 = 18,99 lb/ft
Hmotnost na m (kg/m)=(168,3−7,11)×7,11×0,0246615 = 28,26 kg/m
