Friday evening was interesting. It involved a party with a fair number of odd people tht I barely know, but whose antics were generally enjoyable. However, towards 12 PM ish, the party started getting depressing, with a number of drunk and depressed people shambling about, and lying comatose. So I turned to other persutes to entertain myself.
The party itself was mostly out-of-doorsy, being covered by a set of hastily strung up tarpolens. They did not keep out all the rain, and let in most of the wind. Seeking to quantify the shelter value of such a setup, i theorised the "Baird Shelter Coefficient". This can be calculated simply :

The sqare root of ( [ (Rain flow rate in cubic meters per square meter per second {ie- meters per second} outside the tarpolen)/ (Rain flow rate {meters per second} inside the tarpolen) X (Wind flow rate above the tarpolen {again in meters per second})/ (Wind flow rate beneath the tarpolen {Meters per second}) ] squared + (temperature inside minus the temperature outside) squared ) times the correlation constant

In symbol form R is rain flow rate
W is the wind flow rate
T is the temperature
M is the correlation constant

Hmmmm.

Damn.
Dunno how to paste in pictures.
I shall leave you to work it out and mebe paste it in on a later date.

Chow.
