Taken from a nifty little book called "Flights of Imagination" and
introduction to Aerodynamics by Wayne Hosking.
The Standard textbook formula for lift is:
L = .5(Lc)(p)(s)(V*V)
where L = Lift force
Lc= lift coefficient
p = Air density
s = Area of the kite (square meters)
v = Wind Velocity (m/s)
The weight of the kite (W) is related to its mass (M) by W = Mg where g
is the acceleration due to gravity (g = 9.8 m/sec*sec). Also, typical
values for the lift coefficient and air density are 0.6 and 1.3Kg/m.
With thes values, the lift formula can be rearranged to predict wind
speed for a kite to fly:
v = (5 meters/second)the square root of M/S
wish I had the right stuff to show formulas correctly. but you should have
a starting point from here.
