WOODWORKING QUIZ for 30 July 04

[Ralph Jones]

Good Evening Friends,
What is meant by the term, "dewpoint?"

Respectfully,

[duckman]

Hmmm.. High School was a very long time ago but here goes..

Dewpoint is the temperature and humidity at which the air can no longer hold moisture vapour so the moisture is released as fog or possibly rain?

Pick Me!! Pick Me!!

It's at that temperature where,
the amount of liquid becoming a gas;
is the same as the amount of gas becoming a liquid.

For that particular liquid/gas.

Am I correct?
If so, I've learnt something at work :eek: :eek:

The definitions above are correct - just a little more info: Dewpoint will affect the drying characteristics of wood (so is relevant to the forum!), but as a private pilot, dewpoint is a very important measure. It tells you the likelyhood of fog formation (or icing in winter). Dewpoint depends on pressure (and hence altitude) and is normally quoted on aviation weather forecasts.

Good Evening Friends,
Several interesting answers to day and you all have the right idea.
The "dew point" is the temperature at which the air is completely saturated with moisture. Any lowering of the air temperature will cause condensation to occur.

Thank you for your support.

Where I work the Dew Point is somewhere up around 300-450*C

In a Power station running a Super Critical Boiler.
