Corona Treater Power hnuaia Core Formula awm chu
Treatment dose chu watt density anga tarlan a ni: treatment surface minute khata square centimeter khata watts.
Watt density (W/cm2/min)=Power hman (W) ÷ [ Web zau zawng (cm) × Line chak zawng (cm/min) ].

Entirna hnathawh: 1.6 m a zau line chu 250 m/min-in a kal a, generator chuan 24 kW a hmang bawk.
- Web zau zawng=160 cm
- Line chakna=25,000 cm/min
- Minute khata enkawlna hmun=160 × 25,000=4,000,000 cm2/min
- Watt density=24,000 ÷ 4,000,000=0.006 W/cm2/min
