What is the formula of finding the speed of a vehicle by

Of course the speed is in inches per minute if D is in inches, but that's no bother. To get inches per hour, multiply by 60. To get mph, you need to divide by the number of inches per mile, which is 63360. So all told, divide by 63360/60=1056. So take diameter in inches, multiply by pi, multiply by rpm, divide by 1056.

Theory of Flight MIT

Theory of Flight. Lighter-than-air craft, such as the hot air balloon, work on a buoyancy principle. They float on air much like rafts float on water. The density of a raft is less than that of water, so it floats. Although the density of water is constant, the density of air decreases with altitude.
