A traditional hair dryer evaporates water from your hair using a stream of heated air blown into the hair. The temperature and time of drying must be carefully controlled to avoid damaging the hair shafts. Newer hair dryer technology uses electrical charges (ions) to strip water molecules from your hair, which reportedly is faster and less likely to damage hair (split ends, frizzy, dull). Reportedly it removes moisture from the surface of the hair while leaving some moisture within the hair shaft for improved sheen. Some manufacturers claim that using crystals of the mineral tourmaline in the construction of the dryer produces a superior electrical charge, while using ceramic heater elements produces superior hot air, so the latest high-priced dryers boast "Ceramic Tourmaline Ionic" technology.
A voltage is connected across a heating coil and a current flowing in the heating coil creates heat (just like in an incandescent light bulb). A blower motor helps disperse the heat from heating element to the area to be heated, like the hair. The hot air combined with the blowing help evaporate and blow the dampness from the hair.
An open loop system has no feedback to control what is being "done" by the system or device. In a hair dryer the work being done is to dry something, typically your hair. However, the hair dryer has no way of knowing how "dry" your hair is getting and adjusting the speed or heat to dry faster or slower. It is the person at the controls that makes this judgment and not the device. However in a hair dryer there may be a heat sensor that turns off the heating element so it doesn't get too hot. This is a feedback system within the dryer, but has nothing to do with how dry your hair is getting.
the main part of the hair dryer is the fan which blows the heat towards your hair. this will make your hair dry.
Dry your hair when it is wet.
They can also function as a cheap alternative to a heat gun.
Yes, this is the purpose of a hair dryer.
It depends on the model, if the hair dryer is a 1500 watt hair dryer, then it uses 1500 watts on high heat. If the hair dryer is a 2000 watt hair dryer, then it uses 2000 watts on high heat. Hair dryers come in all different size wattage, so it depends on the size wattage of the dryer. Most hair dryers are 1500 watts.
Trash it!!! The hair dryer has a short and will burn up. Since hair dryers are cheap, toss it in the trash.
A 100 watt light bulb does not cost more that a 1200 watt hair dryer. The average price of a light bulb is about 90 cents whereas a hair dryer can range up to 20 dollars.
around 3000
The motor is housed at the back of the hair dryer just behind the vent.
My CHI hairdryer stopped working. Who can repair them?
Electrical energy is turned into heat and wind energy.
the hair dryer was invented by Alexandre in 1890 but the first had held hair dryer was invented 1971.
To dry wet hair...(Hint: HAIR DRYER)
the first hairdryer was actually the vacuum cleaner. After that in 1920 was the first patented hair dryer which didn,t work well. Then in the 50's was the first properly working hairdryer.
Yes, this is the purpose of a hair dryer.
a hair dryer is basically used to dry wet and damp hair!
A little obvious, isn't it? Hair-DRYER. It drys your hair.
The heat from the hair dryer acts like hair straightners i suppose?
My hair dryer is broken and needs fixing. Where can I find a company that provides hair dryer repair?
You can demonstrate Bernoulli's principle using a hair dryer and one or two Ping-Pong balls. Simply turn on the hair dryer and point it upwards. Then place the Ping-Pong ball in the air stream so it the upward force of the hair dryer balances the force of gravity. The ball will appear to levitate. This demonstrates the Bernoulli principle that fast moving fluids are at a lower pressure than slow moving fluids. Air from the hair dryer is at a lower pressure than the outside air. So a ball that is smaller than the air stream can be balanced in it.
