Qaybta-Cinwaanka
1 Soocelinta isku-darka iskuxirka iyo qaaciddada wareejinta dhererka L / kg L1 = 143m / (d * d)
2 Isku-darka isku-dhafka ah iyo qaaciddada wareejinta dhererka g / l Z = (t * w-0.2146 * T2) * 8900 * 1000/1000000
3 Aagga isku-dhafka ah ee silig xasaasi ah mm2 S = t * w-0.2146 * t2
4 Miisaan culus oo isku-dhafan iyo qaaciddada dhererka L / kg L2 = 274 / (D * D * 2 * Strands)
5 Iska caabbinta silig xasaasiyadeed Ω / l R = r * l1 / s
6 Qaaciddada 1aad: iska caabbinta fiilada Ω / l R20 = rt × α × 103 / l3
7 Qaaciddada 2: iska caabbinta fiilada Ω / l R2 (ω / km) ≦ r × 1.03 ÷ × × × 1000
L1 Dhererka (m) R1 Caabbinta (ω / m)
L2 Dhererka (m / kg) r 0.00000001724ω * ㎡ / m
L3 Dhererka (km) R20 Cadaadiska ka hortagga ah ee 1km at 20 ° C (ω / km)
M Miisaan (kg) Rt Caabbinta t ° C (ω)
D Dhexroor (mm) αt Xanuudka Heerkulka
Z Miisaan (G / M) R2 Caabbinta (ω / km)
T Dhumuc (mm) r Caabbinta 1 mitir hal-strand-strands oo la gartay silig naxaas ah
W Ballac (mm) s Strands (PCS)
S Aagga isugeynta (MM2)
