English unit for power?
The basic SI unit of power is the Watt. Power can also be measured in microwatts, milliwatts, kilowatts, Megawatts etc. There are alternative ways of measuring power, especially for heat energy, like calories per second or BTU per hour.
The steam engine used to power other machines was invented by?
James Watt.
How do you convert MWh to MW?
MWh is a unit of energy whereas, MW is a unit of power. Energy and power are two words often confusingly interchanged. Energy is the amount of work done, whereas power is the rate of doing work. One MWh (Mega Watt Hour) is a million watts of power applied over the period of an hour. One MW (Mega Watt) is a million watts. 1 Watt is 1 Joule per second. To convert MWh to MW, you should divide MWh by the time applied in hours. MWh = MW * Hours, and respectively MW = MWh / Hours E.g. Some electrical equipment used 84 MWh is the total energy measured by a electricity meter over 12 hours operation. What is the power rating of the equipment in MW? 84 MWh / 12 hours = 7 MW
Is a kWh a unit of power or unit of work?
kWh (kilo watt hours) is a unit of energy.W is a unit of power and h is a unit of time. power x time = work. Therefore kWh is unit work, or energy. The k is no unit at all, it is simply short for kilo, a multiplier by one thousand.
How much money can you save by turning off lights?
The amount of money can you save by turning off lights is directly determinant on how many lights you have running, at what power rating and for what amount of time. For instance if you have one light bulb with a 75 watt rating running for 100 hours that will be 75kW-hours (where kW is equal to W x 10^3 or W x 1000) kilo-watt hours are a typical measurement in household meter boxes. If your electricity is being supplied at $0.08/kw-h then it is simply 75 x 0.08 which is equal to $6.00. therefore you can see that, with numerous lights, turning them off can offer a substantial saving over a long period of time, not to mention an important environmental benefit.
What is the name of the horse that James Watt used to determine horsepower?
James Watt didn't use a horse to find horse power
Who used a horse to estimate the value of power?
James Watt
How many watt power in horse power?
1 horsepower equals 745.69987 watts. Scroll down to related links and look at "Electrical Power" and "Energy".
How many kw does an 25hp engine produce?
If I did the conversion right it is 18.64 since one watt is equal to 0.001341 horse power.
What is 1 unit of power?
You are probably confusing energy for power. A 'unit', which is short for 'Board of Trade Unit', is equivalent to a kilowatt hour, which is used to measure energy, notpower.
What is named after James Watt?
james watt is remembered for measuring the power of his steam engine: his test with a strong horse resulted in his determination that a "horsepower"was 550 foot-pounds per second. The unit of power in the metric system is called the watt; one horsepower equals 746 watts.
What was the contribution of James watt in the field of science?
James Watt was a Scottish inventor and mechanical engineer. He improved the steam engine, developed the concept of horse power and invented the copying machine.
1 watt hour equals how many watts?
1 watt-hour equals 1 watt times 1 hour, or 3600 joules.
How many 400 watt metal halide lamps will operate off a 1000 watt ballast?
It will power two 400 watt lamps.
If you buy a two sub woofers with 400 Watt continuous and 1200 watt peak power how many watt amp should you buy?
800 watt should be fine
Why did James Watt designed experiments in horsepower?
Watt was competing with horse power for business. He pitched his new steam engine in terms of the number of horses it could replace.
How many 100 watt light bulbs can run with a 1500 watt power inverter?
we can use 12 no's
