An electric motor under steady load draws 9.7 amperes at 110 volts delivering 1.25 hp of mechanical energy What is the rate of the heat transfer from the motor in kW?
As the motor is drawing 9.7×110 = 1,067 watts (or 1.067 kW), and delivering 1.25×746 watts (or .9325 kW) of mechanical energy, it should release 1,067-932.5 = 134.5 watts (or .1345 kW) of heat.
What is 60w light bulb?
a normal incandescent 60 watt light bulb uses 60 watts of electricity to produce 20 watts worth of light, and 40 watts worth of heat. It is more of a heat bulb than a light bulb. it is great if you can capitalise on the free heat, but if it is not cold in your house, turn it off. is there a better bulb? no. why are they ideal? cheap (as low as 10 cents for the el cheapos), never change shape/design/size/compatability, make pleasant light I could go on for an hour, but the best bulb is the cheapest.
What does a 220 resistor do?
The watt rating of a resistor is directly proportional to their physical size. Resistors generate heat just like any resistive load. Small resistors usually are rated at 1/4 watts, larger resistors about 1/4 in diameter have a 2 watt heat dissipation capacity. Ceramic wire wound resistors are wound on a tube form so that there is more surface area and cooling air can pass up through the tube. These types of resistors can dissipate up to 50 watts of unwanted heat. <<>> None. Resistors do not have watts. Watts, ohms, amps, volts, farads... are all ways to measure electrical properties, and while there are interrelations, watts refer to the total amount of energy that a device consumes or produces.
Difference in dimmer switch heat 600 watts or 1000 watts?
A dimmer switch is used for lighting loads and not heating loads. The wattage rating on a dimmer switch is what the manufacturer recommends as the maximum load that the switch can handle. For example if you have ten 100 watt lamps, the total load wattage would be 1000 watts (10 x 100). Too much load for a 600 watt rated dimmer switch but not for a 1000 Watt rated dimmer switch. So you can see that the rating on a dimmer switch governs the maximum wattage load that can be connected in the circuit that is to be controlled.
Does 1000 watts of heat at 110 equal 1000 watts of heat at 220?
Yes
Does a compact fluorescent lamp use 60 watts the same as a standard lamp?
40 watts is 40 watts, that is what you are paying for. However, an incandescent bulb uses the 40 watts to make light and heat. The compact bulbs make more light and less heat for the same wattage. To actually save, choose a lower wattage that will give acceptable light levels.
Why do computers give out heat?
Processors handle electric switches (transistors) which in their process create heat. Heat sinks are attached along with fans to draw away the heat created
How many watts does a heat lamination use?
The power consumption of a heat lamination machine typically ranges from 300 watts to 1500 watts, depending on the size and capacity of the machine.
A heat pump has a cop rating of 2.5 to 1 if 200 watts of electricity are used to run the heat pump how many equivalent watts are produced?
Since the Coefficient of Performance (COP) is 2.5, for every 1 watt of electricity input, the heat pump produces 2.5 watts of heating or cooling output. Therefore, if 200 watts of electricity are used, the heat pump would produce 2.5 times 200, which equals 500 watts of equivalent heat output.
How many watts of air conditioning removes one watt of heat?
54 Watts is the eqivianlient to removing 1 watt of heat
How much heat is in 1000 watts?
1000 watts is a measure of power, not heat. Power is the rate at which energy is used or transferred. To determine the amount of heat generated by 1000 watts, additional information about the time over which the power is used or the efficiency of the system is needed.
Why does the ENIAC computer give off so much heat?
the eniac and other computers like to give off so much heat because they use thousands of vacuum tubes that took up lots of space and gave a great deal of heat just like a light bulb does.
How many watts are needed to heat 2.5 liters of water from 0c to 100c?
"Watt" is a rate of moving energy. Anynumber of watts can heat your liters,but the less watts you use, the longer the job will take.
How much heat is produced by all the electrical appliances in a security office?
That depends on the "appliances" in the security office. Generally, the easiest way to determine the amount of heat given off would be to add up the total wattage of all appliances/computers/monitors... and that would be the total. The electrical energy is almost all, eventually converted to heat. For example, if all of the computers, monitors and other equipment add up to 5,000 watts of electricity, all 5,000 watts is being converted to heat. With ONE exception: if one of the devices happens to be an AC unit, and the AC unit is exhausting heat to the OUTSIDE of the security office, that would reverse some of the heat build-up.
How can a heat lamp produce heat?
it depends what kind of bulb you have in it. how many watts??
How many watts are required to heat one gallon of water one degree?
2.4705 watts/hour
