Power factor calculator. Power factor calculator. Calaculate power factor, apparent power, reactive power and correction capacitor''s capacitance. This calculator is for educational purposes.
· How to calculate power factor. To calculate power factor, you need a power quality analyzer or power analyzer that measures both working power (kW) and apparent power (kVA), and to calculate the ratio of kW/kVA. The power factor formula can be expressed in other ways: PF = (True power)/ (Apparent power) OR. PF = W/VA.
Vibratory feeders are basically applied to a control function to meter or control the flow of material from a hopper, bin, or stockpile, much the same as an orifice or valve control flow in a hydraulic system. In a similar sense, feeders can be utilized as fixed rate, such as an orifice, or adjustable rate, as a valve.
