Los laij qhov hnyav ntawm aAluminium ChevLos ntawm nws qhov dav, txheej diam, thiab sab hauv lub taub, koj tuaj yeem siv cov qauv hauv qab no:
(Ntim) {= 3}, 14/4 * (Od ^ {{}}}}}}}} {^ 6
(Qhov hnyav hauv [kg]) {= (ntim) * d
Hnyav (kg)=[3.14 / 4 x (od ^ 2 - id ^ 2) x w x d] / 10 ^ 6
Qhov twg:
Od yog lubsab nraudInch ntawm aluminium kauj hauv millimeters (hli) ID yog lub taub sab hauv ntawm lubtooj dawbkauj hauv millimeters (hli) w yog qhov dav ntawm lubtooj dawbkauj hauv millimeters (hli) d yog qhov ntom ntawm cov kilo hauv kilo note ntawm txhuas yog kwv yees li 2700 kg / m ^ 3.
Tus coefficient 10 ^ 6 yog siv los them lub qhov ntev hauv [mm] nrog lub ntim nyob rau hauv [m ^ 3] {3} {3}
For example, let's say you have an aluminum coil with an outer diameter of 1000 mm, an inner diameter of 500 mm, and a width of 1500 mm. Using thecov lus ntawm ib txoj kab keSaum toj no nrog lub ntom ntom ntawm 2700 kg / m ^ 3, peb tuaj yeem suav qhov hnyav ntawm lub kauj li:
Hnyav (kg)=[3.14 / 4 x (1000 {{{41) x 1500Eight (kg)=2384.4375 kg
Yog li ntawd, qhov hnyav ntawm txhuas coil yog kwv yees li2384kg .
