The value of 4.9 kW is equal to 4900 watts. Use the following equation to find the amperage for your question. I = W/E, Amps = Watts / Volts.
Power=V*I. Divide the answer with 1000 and you will have the answer in KW.
KW is bigger. 1000 watts = 1 KW
Both mean kilowatts. The usual notation is kW.
47.79 kW
p.u value=actual value in any unit/base value in same unit
250kva times the power factor gives the kW. the value of power factor angle is needed..

It is 1 x 10-14
Kw is the ionisation constant for water at 25°C which value is 1.0x10^-14. (chemistry)In water at any pH the equilibrium state Kw is defined by and equal to the 'ion product':Kw = [H3O+]*[OH-] = 1.0*10-14at room temperature 25°C
There is one part of the question missing. To find an answer the kW of the heater must be stated. Then the equations used are, to change kW to watts, Kw/1000 = watts. Once that is found then use, I = W/E, Amps = Watts/Volts. This will give you the value in amperage of the heater.
"The pH of PURE water will always be 7." This is false. As the temperature rises for pure water, so does the Kw value. Kw=2.917 x 10^-14. Kw=[OH-][H+]. Kw=[1.708 x 10^-7]^2. -log(1.708 x 10^-7)=6.76=pH
