Rumus Hopulasi Data

1 | Koléksi karangan | L / kg | L1 = 143m / (d * d) |
2 | Kolot beurat | g / l | Z = (t * w 0,2146 * t2) * 8900 * 1000/1000000 |
3 | Wilayah cross-bagian tina kawat segi opat | mm2 | S = t * w 0,2146 * t2 |
4 | Litz kawat batin sareng panjang konversi panjang | L / kg | L2 = 274 / (D * D * 2 * Strands) |
5 | Taya-sésa kawat sépulér | Ω / l | R = r * l1 / s |
6 | Rumus 1: Resistan kawat litz | Ω / l | R20 = RT × α × 103 / L3 |
7 | Rumus: Resistan kawat litz | Ω / l | R2 (ω / km) ≦ r × 1.03 ÷ s × 1000 |
L1 | Panjang (m) | R1 | Resistén (ω / m) |
L2 | Panjang (m / kg) | r | 0.00000001724ω * ㎡ / m |
L3 | Panjang (km) | R20 | Resistan Resistektip per 1km dina 20 ° C (ω / km) |
M | Beurat (kg) | Rt | Risto di t ° C (ω) |
D | Diaméter (mm) | αt | Koefisien suhu |
Z | Beurat (g / m) | R2 | Resistansi (ω / km) |
T | Ketebalan (mm) | r | Resistan 1 méter tunggal-strand berlaku |
W | Lebar (mm) | s | Strandi (PCS) |
S | Wilayah cross-syarat (mm2) |
