keep the kite tethered
This Sankranti, I thought I couldn't comprehend how to fly a kite - ever! Well, as luck would have it, that was a short moment. Simple. I asked my neighbor and he told me how to string a kite. Science from none other than NASA, tell us this: Lift (L) = Cl * A * r * .5 * V^2 The lift L is equal to a lift coefficient Cl times the projected surface area A times the air density r times one half the square of the wind velocity V . Similarly, the drag D is equal to a drag coefficient Cd times the projected surface area A times the air density r times one half the square of the wind velocity V . Drag (D) = Cd * A * r * .5 * V^2 skratch-pad.com tells us this: The lifting force of all kites is produced by deflecting the air downward, the resulting change in momentum producing an upward force. The reason for this is that the air traveling over the top of the curved surface of the kite is going faster than the air passing underneath. Fast-moving air creates...
