Why Water Condenses Over The Wing At Takeoff?

Wed Apr 02, 2003 6:04 am

I know that over the wing there is a region of low pressure, and at high humidity percentages, water vapor becomes visible, but I thought high pressure helps water to remain in the liquid state not the low pressure. Now am I right or am I confused??

The faster flowing air creates a lower pressure, and when pressure drops, so does temperature. And when temperature drops below the local dewpoint, you get condensation. It's not the low pressure that causes condensation, it's the drop in temperature.

JET,
Are you referring to the fact that the same post was on here a few days ago? I remember that too.

Not everyone reads these forums everyday, so questions are likely to be asked more than once. It's good though to do a search before asking something that might have been answered before.
