How can the heat generated by electrical equipment be estimated?
The heat load for, say, an industrial production space is calculated by summing the heat loads of the electrical equipments installed. The environmental and HVAC engineering crew obtains the information directly from the equipment manufacturers. In the case of motors, pumps, ovens, dryers, etc., each manufacturer has the statistics available. They are usually not included with the equipment, but may be obtained from the folks who make the units when more precise and detailed workspaces are being considered or set up. It usually only takes a few phone calls or faxs to get the ball rolling.
How does being a good conductor of heat and electricity make platinum useful?
Good electrical conductors are useful because they allow electricity to be transmitted greater distances with less loss. This greater efficiency allows more of the electrical energy generated to be used, reducing the amount that must be generated. Good heat conductivity is less useful than good electrical conductivity, but it does make it easier to keep wires and cables cool, which further increases their electrical conductivity.
What are the causes of an electrical fire?
The root cause is usually based on the heat generated by poor or broken contacts in equipment or wiring. Certainly an electric arc will create a lot of heat, and it will cause insulation and anything else close to begin to burn. The cause may not disappear right away, too. An arcing wire can sustain a fire, even if it is extinguished. It can re-ignite at the next arc. We usually de-energize affected equipment or…
Why is a heat-sink used on some equipment?
The main purpose of a heat sink is to dissipate excessive heat away from the device that it is attached to. Some small integrated circuit components are so physically small that an over excess of heat generated by themselves would destroy the device. The heat sink is placed on the IC to prevent this from happening.
What does a thermal power plant do that a coal power plant doesn't?
In a thermal power plant, the conversion of thermal heat into rotational energy is achieved. This can be achieved by using the thermal heat from burning coal or from burning oil or from burning gas or from steam generated by solar means (insolation). In a coal power plant the thermal heat obtained from burning coal is converted into rotational energy, which drives the generator and eventually, electrical power is generated.
Is there a coating you can put on electrical wiring to reduce the temperature?
Not that I have ever heard of. Electricity produces heat and heat is the cause of most electrical problems. The wire is heating because too much current is being conducted for the size of the wire. You need to either replace the wire with something larger or add another wire. The temperature of the wire has nothing to do with the coating, the heat is being generated inside the wire when excessive current is passing…
What converts electrical energy to heat energy?
Short Answer: Whenever electrical current encounters resistance, heat is generated. Many home heating appliances (e.g. toasters, water heaters) work on this principle as well as tools (e.g. soldering iron, hair dryer) and even industrial furnaces. In each case, the resistance doing the heating has its specific performance characteristics that is has to meet, but the underlying scientific principle is the same. More: The simplest electronic component is probably the resistor. A resistor has no purpose…
Explain the methods of using one piece of electrical equipment safely during the conditioning treatment service?
The methods of using one piece of electrical equipment safely is to check that the equipment (climazone) has been PAT tested, check all cords for breakages and loose wires, check the heat settings are intact and working correctly. When using the climazone on a client for a conditioning treatment ensure that the heat settings aren't too high and that the clients head isn't to close to the equipment, also to ensure that the cords aren't…
What is used to convert electrical energy to heat?
The simplest electronic component is probably the resistor. A resistor has no purpose other than to "resist" the flow of electricity. It performs no function other than turning electrical energy into heat energy. (Usually the purpose is not to generate heat, but to control voltage or current and the generation of heat is secondary.) If a current I flows through a resistor R, then the rate power, P, is P=I2R. Similarly, if a voltage drop…
How is the electricity generated in a coal-fired power plant?
in your question itself you have said that coal-fired yes electricity is generated by burning coal a large amount of heat is generated as a result. this heat energy is used to heat water inside the boiler tubes. the water is converted to dry saturated steam at this state the temperature is about 540 degree celcius and pressure about 140 kg/sq.cm. this steam is made to expand in a turbine whose shaft is coupled to…
When an electric fan is turned on what type of energy is electrical energy transformed into?
The electrical energy is converted to kinetic energy and heat. The kinetic energy is first seen in the blades of the fan as they rotate. This kinetic energy is converted to air movement, another form of kinetic energy. The electrical energy isn't fully converted to kinetic energy but turns into heat. This is generated by the magnetic fields of the motor and friction. Both of these are considered to be losses of energy but in…
