Why does air feel cooler when blown through a small area?
The faster air moves, the lower pressure it has (Bernoulli’s principle). So when you blow faster, your stream of air is lower pressure than the surrounding air. Thus the surrounding air fills in the stream. The surrounding air is obviously cooler than the air in your lungs.
Why does air move faster when you blow?
Simple answer: When you blow harder, more surrounding air gets mixed in with the stream of air from your mouth. The faster air moves, the lower pressure it has (Bernoulli’s principle). So when you blow faster, your stream of air is lower pressure than the surrounding air. Thus the surrounding air fills in the stream.
Why does my car AC blow cold air?
If the fans aren’t running at high speed or one fan isn’t running, your AC may blow cold air when you’re moving because enough “ram” air is coming across the condenser coil to keep temperature and pressures low.
Why does the Heat Blow when the car is not moving?
Heat is blowing when the… Heat is blowing when the car is moving, but blows cold air when it’s not. Temp gauge looks normal, and heat blows when car is moving. Coolant level is good. Looking for the thermostat I found a weird piece on top of engine called a coolant outlet housing, has a bleeder valve on top.

Why is my tumble dryer blowing cold air?
Overheated Dryer One of the most common reasons why tumble dryers start to blow out cold air instead of hot, is because it has overheated. This may seem ironic but dryer manufacturers are legally required that the dryer has some sort of way to prevent it from catching fire when it becomes too hot.
Why is the Vauxhall Corsa heater blowing out cold air?
The problem with the heater on the Vauxhall Corsa (as well as the Renault Clio) is often that there is no power from the heaters at all. This issue has nothing to do with cold air coming out instead of heat. This loss of power is also a common issue on the Renault Clio. Or you may have a dirty fan that is stuck.
