Qhov hnyav ntawm cov yeeb nkab hlau ib ko taw yog dab tsi

Qhov hnyav theoretical ntawm cov yeeb nkab hlau yog dab tsi

Yog tias OD thiab WT yog nyob rau hauv millimeters:

Qhov hnyav ib ko taw (lb/ft) = (OD−WT) × WT × 0.01657

Yog tias Sab Nraud Txoj Kab uas hla (OD) thiab Phab Ntsa Thickness (WT) yog nyob rau hauv nti:

Qhov hnyav ib ko taw (lb/ft) = (OD−WT) × WT × 10.69

 

Tus ko taw (lub cim: ft) yog ib chav ntsuas ntev hauv lub kaw lus imperial.

Ib leeg: 1 ko taw (1 ft). 1 ko taw ≈ 0.3048 meters

Plural: 2 ko taw (2 ft). Lub cim "ft" tseem tsis hloov pauv hauv daim ntawv plural.

Yuav ua li cas xam qhov hnyav ntawm 6 nti sch 40 yeeb nkab

6 nti Sch40: OD 168.3 hli thiab WT 7.11 hli:

Qhov hnyav ib ko taw (lb/ft) = (168.3−7.11) × 7.11 × 0.01657 = 18.99lb/ft

Qhov hnyav ib m (kg/m) = (168.3−7.11) × 7.11 × 0.0246615 = 28.26kg/m
