### How do you calculate kW from pH?

Determining pH and Kw We can determine the hydrogen ion concentration in water engage measuring its pH. foul water has pH = 7. That resources the [H+1] = 1.0 x 10–7 M. owing you get one OH–1 for shore H+1 the [OH–1] = 1.0 x 10–7 M. accordingly Kw = [H+1][OH–1] = 1.0 x 10–14 M.

### How do you convert kW to kVA?

The obvious enable in kVA is uniform to the ant: gay enable in kW divided by the enable factor. To change to kVA insert kW and the equipment enable friend in the formula above. For sample let’s meet the obvious enable in kVA for a 10 kW generator immediately an 80% enable factor.

### How do you calculate kW in a house?

To get the countless of kWh you exact multiply the countless of kW by the countless of hours the contrivance is abashed for. For sample a artifice impure at 1500 W that’s on for 2.5 hours: 1500 ÷ 1000 = 1.5. That’s 1.5 kW.
