On an automotive forum, a member made a statement that compressed air won't hold as much moisture as ambient pressure air because the water is "squeezed" out by the pressure and is also, therefore, "drier" air. He pointed to the need to drain water from the tank as proof of the squeezing process. What is the effect of pressure on air's ability to hold water? Does it result in "drier" air? My intuitive reasoning is that "freshly" compressed air can hold more water vapor since it is warmer. The air would not be drier since the volume of air and water in the tank is proportional. I also believe the water in the tank is a result of condensation of the heated compressed air cooling over time, not because it was squeezed out. Who's correct?
