Capacitors for induction heating furnaces

Water flow (per vessel)
-
Formula: Tanδ=P/Q, P=70 x q x Δθ
-
P: actual work, unit watt; Q: capacitor capacity, unit var
-
q: water flow rate, in liters per minute
-
Δθ: The temperature difference between the outlet water temperature and the inlet water temperature (generally 4°C).
-
Minimum water flow q＝(QxTanδ) / 280 (unit L/min) [general value]
