Variation of fan air temperature with angle

The air temperature is probably not different. (Well, maybe very slightly due to the motor resistance heating losses, or other reasons for variations). It's probably the forced convective cooling of ...

Does compressing air increase the average speed of the air molecules?

Think of an individual particle bouncing (elastically) off a wall. If the wall is stationary, the particle will bounce back with the same speed as it collided with. If the wall is moving toward it, it ...

Does compressing air increase the average speed of the air molecules?

Generally, this would tend to increase the average speed of the air molecules- you have done work on the gas and this work has to go somewhere- most likely increasing the average kinetic energy of the ...

Does compressing air increase the average speed of the air molecules?

If you model the gas as an ideal gas, it depends on how you compress the gas. For the ideal gas, the average speed of the molecules is determined by the gas's temperature. When you compress the gas, ...
