Still working through my stockpile of socks, so instead of boring pictures, I bring you Sock Week Day 2!
Today on Sock Week: Windsock!
You've seen them at airports or at the beach, but did you know there are rules about how they work?
(From Wikipedia)
According to the FFA, a 15-knot (28 km/h; 17 mph) wind will fully extend the properly functioning windsock. A 3-knot (5.6 km/h; 3.5 mph) breeze will cause the properly functioning windsock to orient itself according to the wind.
Canada has even more rules:
Per Transport Canada Standards: a 15 knot wind will fully extend the Wind Sock, a 10 knot wind will cause the wind sock to be 5° below the horizontal, a 6 knot wind will cause the wind sock to be 30° below the horizontal.
I'm not sure who is going to be out there with a protractor and Anemometer (used to measure wind speed) to verify, but eh, it's Canada.
