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.

So, we need to use the following formula to get the m as well, but in the SI unit: m = ρV. where, ρ = density of water, kg/m 3 V = chilled water flow rate, m 3 /s. Similarly, the chilled water flow rate measured by devices such as ultrasonic flow meters may be expressed in m 3 /hr, m 3 /min or m 3 /s. So, you''ll need to convert it to m 3 /s ...

Watts (W) is a unit of power used to quantify the rate of energy transfer. It is defined as 1 joule per second. A kilowatt is a multiple of a watt. One kilowatt (kW) is equal to 1,000 watts. Both watts and kilowatts are SI units of power and are the most common units of power used. Kilowatt-hours (kWh) are a unit of energy.
