why window glass does not moist while passing through cloud?

Answer 1

When an aircraft flies through a cloud it is actually being pulled up by an area of low pressure above it's wings and fuselage, this is where the small droplets of water go! Basically it gets sucked out of the way by the airflow.

However, when you fly through a raincloud, the larger droplets do not get pulled away, but DO hit the windows. This is why aircraft have windscreen wipers.

Answer 2

Try skydiving with a camcorder, and then tell me glass doesn't mist up!
While you're increasing to jump altitude (about 13,000 ft), the lense glass get's cold. Once you leave the plane, if you encounter clouds on the way down, the warm moist air in the lower clouds will then condense on the lense of the camera, obscuring your image.
Heating the lense would prevent this, but would take some effort to do.
Try it next time you happen to be falling from 13,000 feet, and just happen to have video equipment with you. Now THAT'S what I call a lab experiment!

Answer 3

It does not moist (condense) because clouds are quite cold, and for them to condense they would need a little bit of heat, where as windows are quite cool resulting in no condensation.
(when both factors are cold, condensation will not occur, in order for condensation to occur either the window, or surrounding air must differ in temperature, one cold - one warm)

Answer 4

Why are you passing your windows through cloud?

Answer 5

You will only get misting if there is a temperature difference between the two sides of the glass.

Answer 6

If both sides of the glass are the same temperature then no condensation will form.

Answer 7

It will if the temperature of the glass is below the dew point of the air.

Answer 8

the surface must be cooled to the dew point before visible moisture will form

Answer 9

If it is warmer than the dewpoint, no moisture will condense on it.

Answer 10

Do you know how cold clouds are!!!!!
