WebHow to make sense of power factor. Beer is active power (kW)—the useful power, or the liquid beer, is the energy that is doing work. This is the part you want. Foam is reactive power (kVAR)—the foam is wasted power or lost power. It’s the energy being produced that isn't doing any work, such as the production of heat or vibration. WebAt 25 °C, the value of Kw is 1.0 × 10 −14, and so: 14.00 = pH + pOH. As was shown in the reaction of a Brønsted-Lowry acid with water, the hydronium ion molarity in pure water (or any neutral solution) is 1.0 × 10 −7 M at 25 °C. The pH and pOH of a neutral solution at this temperature are therefore: pH= -log [H3O+]=-log (1.0×10-7)= 7.00.
