Air at 50% relative humidity is cooled isobarically at I atm absolute from 90C to 25C. (a)
Question:
Air at 50% relative humidity is cooled isobarically at I atm absolute from 90°C to 25°C.
(a) Estimate the dew point and degrees of superheat of the air at 90°C.
(b) How much water condenses (mol) per cubic meter of feed gas?
(c) Suppose a sample of the 90°C air is put in a closed variable-volume chamber containing a mirror and the pressure is raised at constant temperature until a mist forms on the mirror, At what pressure (atm) would the mist form? (Assume ideal gas behavior.)

In this video, the concept of pressure has been explained. The bottle is filled up with water, remove the pipe, and now you can see the clear flow of water from the holes due to liquid pressure.You can see that the second layer is holding the weight of the first layer and the third layer holding the weight of both upper layers, that’s why liquid flows out wider from the third as compared to the first two.At the first hole, water doesn’t roll along the walls; it flows out at an angle.At the second hole, you’ll see that the water flows out at a wider angle as compared to the first hole.At the third hole, we can see that the flow of water is much wider/greater than the other holes.This proves that the pressure at the bottom of the bottle is much more than the pressure at the top layers.
