I-Core Formula Esemuva Kwe-Corona Treater Power
Umthamo wokwelapha uvezwa njengokuminyana kwe-watt: ama-watts ngesentimitha yesikwele ngomzuzu wendawo eselashiwe.
Ukuminyana kwe-Watt (W/cm²/min)=Amandla asetshenzisiwe (W) ÷ [ Ububanzi bewebhu (cm) × Isivinini somugqa (cm/min) ]
Sebenza ngamayunithi angaguquki. Uma ububanzi bunikezwa ngamamitha nesivinini ngamamitha ngomzuzu, phindaphinda kokubili ngo-100 ukuze uguqule ube ngamasentimitha.
Isibonelo esisetshenziwe: ulayini obanzi ongu-1.6 m uhamba ngo-250 m/min kanti ijeneretha isebenzisa u-24 kW.
- Ububanzi bewebhu=160 cm
- Isivinini somugqa=25,000 cm/min
- Indawo eselashwayo ngeminithi=160 × 25,000=4,000,000 cm²/min
- Ukuminyana kwe-Watt=24,000 ÷ 4,000,000=0.006 W/cm²/min
Leyo nombolo ibukeka incane ngoba ifomula ikhiqiza ama-watt ngesentimitha lesikwele ngomzuzu. Kuyinto evamile ukuphindaphinda ngo-1,000 futhi ubike umphumela ngama-milliwatts, noma ukusebenza ku-W/m²/min ngezibalo zezimboni.
