Which cools the air faster a ceiling fan or a air conditioner?
Air conditioner. A fan doesn't actually cool the air - it simply circulates it.
Explain the following statement you feel cooler on a hot day when you turn on a fan even though the air being blown around is hot?
Before you turn on a fan, the air is essentially hot because it is still and there is no circulation byconvection of the air currents. When you turn on the fan, it sparks a circulation where the hot air at the top flows to the opposite side of the room, and then eventually becomes cooler and more dense, falls to the floor, and is pushed back towards the fan by the incoming hot air. So, when you turn on the air, the fan is just cirulating hot air, not making it colder. The air only becomes cooler when it flows away from the fan.
Why does air rush into a vacuum cleaner nozzle?
To understand why air rushes into a vacuum cleaner nozzle we need to trace air flow in the machine. Let's do that. The motor in a vacuum cleaner spins a fan, and the fan moves air. The air intake for the fan is connected to ducting that is routed to the nozzle. As the fan forces air out in its exhaust stream, it creates low pressure on the suction side of the fan. This low pressure (a partial vacuum) is felt along the air path to the nozzle. At the nozzle, outside air pressure forces air into the ducting where air pressure is lower. The moving air has picked up debris and carries it along. That debris ends up in a bag or filtered dirt canister or someplace else where it can accumulate and be collected for disposal. This applies to machines that have bags or filters to get the debris out of the air stream before it goes through the motor to keep it cool. Some machines isolate the motor from the air stream created by the fan, and the motor is cooled by another fan. These "direct" vacuums operate in a way that sees the air stream and the debris pass through the fan and be driven into a bag. The operation of the fan has created a low pressure area along the ducting between it (the fan) and the nozzle. Outside air pressure, being greater than the low pressure created by the fan and ducted to the nozzle, forces air into the nozzle.
Why are there 2 directions on a ceiling fan?
When the fan pulls air up to the ceiling it pushes warm air back down to heat the room. Turn the fan the other direction and it send a cooling breeze.
What puts out more air- a two blade fan or a four blade fan?
four blade
What is a fan?
A fan is a device used to induce airflow and generally made from broad, flat surfaces which revolve or oscillate.a fan ir something that gives you air when its hot
How does a air move?
a fan moves air with fan blades.
How do you get to the roof to fix the air conditioner on poptropica?
If you mean the nightclub's air conditioner on game show island, then you don't have to fix it. You have to go to the factory (all the way on the left) and turn on its power. One of the factory employees gives you a fan, and you use that fan on the manager of the nightclub.
What is the difference between a still air and forced air incubator?
still air incubator is no fan . force air have fan
When a fan is switched on in a closed roomIs it become cool or hot?
A fan, by itself, neither warms or cools the room. However the increased movement of air ensures the air is circulated and the temperature equalised. It also gives a cooling effect to the body as it carries away heat more efficiently than still air.
Where does the air of a fan come from?
the back of the fan
In a hot climate area what are the pros and cons of continuously running the air conditioning fan?
the true benifit of running the indoor fan continuously is it helps reduce the air stratification in the structure. [ie. hot air stays at the cieling and cool air at the floor.] this gives a greater comfort level in the structure. The down side of running the fan continuously is the increase in electrical usage. some people believe running the fan continuously is harmful to the motor, however most experts will agree this is not true.
How does a fan moves?
a fan moves air with fan blades.

Why was the electric fan invented?
A 2 blade fan was invented in 1882 by a 22 year old named Schuylar Wheeler. The fan was used to cool the inside of homes.
Does a ceiling fan take the moisture out of a room in the winter?
No, the ceiling fan will not get the air temperature cold enough to condense the moisture in the air from a gas to a liquid. The only thing that takes the moisture out of air in the room is a dehumidifier. The second choice is an exhaust fan vented to the out side of the building. With an exhaust fan the air has to be replaced by new air. If the humidity of the outside air is the same or higher that the air inside then the exhaust fan will not do the job.
Does the sun gives light and air?
It gives light but not air.
