1 Kulemera kwa Wirepr ndi Kulemera Kwakukulu ndi Kutembenuka Kwakutali L / kg L1 = 143m / (d * d)
2 Matenda a kumata g / l Z = (t * w-0.2146 * t2) * 8900 * 1000/1000000
3 Malo am'mphepete mwa waya wamakonso mm2 S = t * w-0.2146 * t2
4 Mafuta a Litz L / kg L2 = 274 / (d * d * 2 * shands)
5 Kukana kwa waya wamakani Ω / l R = r * l1 / s
6 Formula 1: kukana kwa Witz waya Ω / l R20 = RT × α × 103 / l3
7 Formula 2: kukana kwa Witz waya Ω / l R2 (ω / km) ≦ × 1.03 ÷ s × 1000
L1 Kutalika (m) R1 Kukana (ω / m)
L2 Kutalika (m / kg) r 0.00000001724EC * ㎡ / m
L3 Kutalika (km) R20 Kutsutsa pa 1km pa 20 ° C (ω / km)
M Kulemera (kg) Rt Kukana ku T ° C (ω)
D Mainchesi (mm) αt Kutentha Kwabwino
Z Kulemera (g / m) R2 Kukana (ω / km)
T Makulidwe (mm) r Kukana kwa 1 mita imodzi-chingwe chophatikizika chamkuntho chamkuntho
W M'lifupi (MM) s Zovuta (ma PC)
S Malo oyambira (MM2)
