Why does air blown by a fan feel colder than the other air in the room?
In: Physics
My daughter, studying to become a civil engineer, had an exam where a question was (paraphrasing) “in a static room with a fan, will the temperature of the air increase or decrease?” They also gave some pertinent numbers to work with so they could do the relevant math work, but that was the gist of the general question. She said several wrote that the air would cool down and then they came up with some math to make it work in their heads, IDK. Of course we know that the temperature of that room will increase because of the heat the motor gives off, and the only cooling that is happening is by removing the boundary layer off the skin of a person.
