I was just listen to audio osmosis as a review and they were talking about how the Temperature decreases as the fluid moves faster. Can anyone explain how to make sense of that?
Temperature decreases as the fluid moves faster?

I always thought that segment was a little screwy on AO.
I remember it this way:
As fluid velocity increases, pressure drops. Pressure is caused by the collisions of the molecules of the fluid against the container. Temperature is a measurement of the random translational motion of the molecules. As pressure increases, so does temperature. Therefore, as fluid velocity increases, temperature decreases.
Or a more qualitative way to remember faster air=lower temp is that we pucker our lips before we blow on hot soup.

I can't remember perfectly, but didn't Audio Osmosis use something along the lines of the following explanation?: Both velocity and temperature are a measure of kinetic energy so it turns out to be something like a transfer of KE.
