Signature

Hi, your signature does not seem to point to your "User:" or "User talk:" page. IMHO this isn't very desirable; what do you think? --Kjoonlee 09:15, 30 July 2006 (UTC)

Hi, thanks for making that change. I thought you might be interested in this policy: WP:SIG#Important considerations --Kjoonlee 07:52, 2 August 2006 (UTC)

All links to external website in my signature have been removed to the best of my knowledge. Anthony Chessick 15:09, 7 August 2006 (UTC)

Unsigned Comments Relocated Here

Unsigned Comment - "This is a misunderstanding of mechanics; and analogy would be a cue hitting the cue ball on a pool table, that cue ball then hits into the pack, the cue has supplied the energy to split the pack, but the force felt at the cue is only the reaction from hitting the cue ball, the other balls had no reaction with the cue. This is the same as a wing in a gas."

Reply - Splitting hairs. The mass of a few atoms, reacting like billiard balls, is of little use in supporting a 500 ton aircraft. If it is intended to aggregate them, fine. Just aggregate them enough and you are following in the correct logic presented. You will find sooner or later that looking at the picture with this fine a view is not necessary.

Unsigned Comment - (Lost the text in the computer somewhere, sorry. The question was about computing the exact tonnage of air mass flowing through a 1.5 megawatt turbine at rated wind speed.)

Reply - Here is the math. The rotor diameter is 75 meters and the wind speed is 30 mph or 44 feet per second. The assumption is that all the wind upstream of the rotor goes through it without any bypass around its outside circumference, which occurs but is neglected here. 3.2808 feet = 1 meter. The density of air = .0765 #/ cubic foot.

((75 x 3.2808)/ 2 )^2 x pi = 47552.3 square feet rotor area

((47552.3 x 44 x .0765)/ 2000 #s per ton) = 80.03 tons per second Q.E.D.
