How many units per hour utilized by a 45kw motor?
watt (w) means joules per second. kW (kilowatts) means thousands of joules per second. Multiply that by 3600 to get the joules used per hour.
How many kilowatt hours in one tetra joule?
1 kilowatt hour = 3,600,000 Joules 1 Tetrajoule = 1,000,000 Joules 1 kilowatt hour = 3.6 Tetrajoules
How many BTUs are generated per hour by a 10kW PV Solar Power Plant?
Well, unfortunately there are different BTUs, each a slightly different quantity of energy.The BTU (ISO) is 1054.5 joules exactly. Let's use that one, and avoid some rounding.10 kW = (10,000 joules/second) x (3,600 seconds/hour) x (1 BTU/1,054.5 joules) = 34,139.4 BTU/hour
How many units consumed per 24 hours of megawatt mot er?
Watt, kilowatt, or megawatt are units of power (energy/time). A watt is 1 joule/second. A kilowatt is a thousand joules per second. A kilowatt is also 1 kWh/hour (kilowatt-hour / hour). Since you would usually pay per kilowatt-hour, you might be more interested in the number of kilowatt-hours. A megawatt is a million joules per second - or a thousand kWh/hour.
How many watts per hour to equal 1000 btu's?
The energy unit is not watts per hour, but watts times hour, simply called watt-hours.One BTU is equal to about 1055 Joules or Watt-seconds; that is about 0.293 watt-hours. Actually there are different definitions of the BTU.The energy unit is not watts per hour, but watts times hour, simply called watt-hours.One BTU is equal to about 1055 Joules or Watt-seconds; that is about 0.293 watt-hours.

How many watts does a light bulb use per week?
Your question is rather like asking "How many miles per hour do you do in a week?" You don't consume watts over time, it's a measure of how many joules of energy you consume over time.
One kilowatt equals how many btu per hour?
A BTU is about 1055 joules. A kilowatt is 1000 joules/second, so it is 3,600,000 joules/hour. Dividing that by 1055 joules gives you the equivalent of about 3400 BTU/hour.

How many kilowatt hours in one tetra joule?
1 kilowatt hour = 3,600,000 Joules 1 Tetrajoule = 1,000,000 Joules 1 kilowatt hour = 3.6 Tetrajoules
1 watt hour equals how many watts?
1 watt-hour equals 1 watt times 1 hour, or 3600 joules.
How many joules are in a kWh?
1 kWh = 1,000 watt-hour1 watt = 1 joule per second1 hour = 3,600 seconds(1,000 watt-hour) = (1,000 joule/second) x (3,600 second/hour) = 3,600,000 joules
How many Joules of electrical energy does a 100 Watt light bulb consume from the electrical supply in 2 seconds?
Watt means joules/second. It refers to the amount of energy a device uses, in this case. Multiply the power (in watts) by the time (in seconds) to get the energy (in joules).
How many gallons an hour does a A380 consume?
About 50,000 to 65,000 Gallons
How many joules are there in a kilowatt-hour?
These do not have the same units. 1 kilowatt hour per meter cubed is in kg m-1 s-2 1 kilojoule per kg is in m2 s-2
How many joules does a 800 watt toaster consume in 2 minutes?
Energy = power X time. 800W X 120sec = 96000J
How much energy does a 100 watt light bulb emit in one minute?
I would have to guess, 100 watts. Power consumed is equal to P I E. P = Amps (I) X Volts (E). Power is measured in watts, or typically, as read on your energy bill, Kilowatts (kw, where 1 Kw = 1,000 watts). So, 100 watts/120V (which is the typical American system) = 0.833 amp (I). Your typical power meter, by which the power company reads your monthly bill, measures amps. Also, 100 watts is 1/10 Kw, or 0.10 kw/hourAnswerFirst of all, you do NOT consume power; you consume energy. Energy is measured in joules, so power is measured in joules per second, which is given a special name: the watt.So there is no such things as 'watts per hour', as this would mean 'joules per second per hour' which, obviously, is nonsense!So, your question should ask, "How much energy is consumed by a 100-W lamp in one hour?" Well, if one watt represents one joule per second, then the lamp will consume 100 x 60 joules in one minute and, therefore, 100 x 60 x 60 joules in one hour. That is, 360 000 joules.Electricity companies usually measure energy in kilowatt hours, rather than in joules. A kilowatt hour is defined as "the energy consumed, in one hour, at a rate of one kilowatt'. You can think of a kilowatt hour simply as being a very big joule! Since 100 W is 0.1 kW, we can therefore say that the lamp must consume 0.1 x 1 = 0.1 kilowatt hours during a period of one hour.
How many kw in a kj?
1 kWh is a kilowatt-hour, in other words 1000 watts for one hour. That is 1000 Joules per second, for 3600 seconds. So 1 kWh is 3,600,000 Joules, or 3600 kJ.
