1 gallon of water weighs 8.34 pounds. It takes I BTU to change the temp of 1 pound of water 1 degree F. So for 1 gallon it takes 8.34 BTU. It takes 3412.14 BTU to equal 1 KWH. So 8.34 Btu x (1KWH / 3412.14 BTU) = 0.002444 KWH
0.6726
1 Mwh = 1000 Kwr
To raise the temperature of one cc of water requires i calorie of heat . you did not specify the volume.
New energy star models are about 470 kWh per year.
KWH
0.001167 kWh/°C/l at 100% efficiency.
1 mwh = 1000 kwh hence 4 mwh = 4000 kwh
1 kwh = 3,600,000 Joules
100 kWh
about 10,000 KWh
approximately 40 kWh
1 PJ equals 277 777 777.78 kWh
To find kWh a time frame has to be given. That is what the h in kWh stands for.
Use the equation. Kw x Hours = KWh so take 10Kw multiplied by 8,760 hours and you get 87,600 KWh. 10Kw x 8,760 hours = 87,600 KWh
kwh consumption of the driver of the pump will increase.
Dinorwig is a 'pumped storage' hydro power facility. It has a capacity to produce 1.89GW of electricity, which equates to 6.8TWh. I terms of kWh, this would be 6.8E9 kWh or 6,800,000,000 kWh. (6.8 billion kWh).
Hi I believe it is 277.7 kWh per Gj. Cheers
