Anemometer is blowing on the back of the cup on the opposite end of the cross. Since a hollow hemisphere has a drag coefficient of .38 on the spherical side and 1.42 on the hollow side, more force is generated on the cup that is presenting its hollow side to the wind. Because of this asymmetrical force, torque is generated on the axis of the anemometer, causing it to spin. Theoretically, the speed of rotation of the anemometer should be proportional to the wind speed, because the force produced on an object is proportional to the speed of the fluid flowing
What Does the K Stand For? feel less like real people than excuses to weave in a few good dad jokes". Overall, Elan found, "What lifts the show are the elements of diaspora life weaved throughout, as when Aunty Princess visits from Nigeria and accuses Virginia [Stephen's mother] of cultural betrayal ('You have adopted too many fine and fancy British ways').
