A hair dryer (the handheld type also referred to as a blow dryer) is an electromechanical device that blows ambient air in hot or warm settings for styling or drying hair. [ 1 ] [ 2 ] Hair dryers enable better control over the shape and style of hair, by accelerating and controlling the formation of temporary hydrogen bonds within each strand.
Air jet loom. An air-jet loom is a shuttleless loom that uses a jet of air to propel the weft yarn through the warp shed. [1] It is one of two types of fluid-jet looms, the other being a water-jet loom, which was developed previously. [1] Fluid-jet looms can operate at a faster speed than predecessor looms such as rapier looms, but they are not ...

The electric supply is used to start the motor as well as for ignition. The voltage is usually built up slowly as starter gains speed.
A hot roller or hot curler is designed to be heated in an electric chamber before one rolls it into the hair. [2] Alternatively, a hair dryer heats the hair after the rolls are in place. Hair spray can temporarily fix curled hair in place. In 1930, Solomon Harper created the first electrically heated hair rollers, then creating a better design ...
Hand dryers have been popular with industries for their apparent economies. According to manufacturers, hand dryers can cut costs by as much as 99.5% (for example a company may spend $2340.00 per year on paper towels, where as the hand dryer expenditure would be as low as $14.00 per year—this will vary according to the cost of paper towels and electricity).
An airbreathing jet engine (or ducted jet engine) is a jet engine in which the exhaust gas which supplies jet propulsion is atmospheric air, [1] which is taken in, compressed, heated, and expanded back to atmospheric pressure through a propelling nozzle. [2]
