Wind turbines can achieve a very high spinning speed. And as mentioned already, the length of the blade has a role to play. In many cases, the tip of a blade can easily hit a speed of 100mph, and it often goes up to 180 mph, depending on the velocity of the wind. When speaking of wind turbine speed, it is important to get an idea about the ...

Example 26 inch bandsaw wheel: 26 x = then divide by 12 is feet around the wheel. So if I want my band to run at 5,500 then I divide 5,500 by = 808. 808 rpm is the speed I want to turn the shaft of the drive bandsaw wheel. In Conclusion: The bandsaw blade needs constant speed with torque more than it needs speed.

If we keep rpms constant, Surface Speed is directly proportional to diameter. The 1/16″ endmill at the bottom is travelling 1/8 as fast in terms of Surface Speed as the 1/2″ endmill at top. Hence, to achieve a given Surface Speed, small tools will have to spin faster and large diameter tools will have to spin slower.

To determine this (you might need to break out the calculator), simply multiply the recommended cutting speed by the value (round up to 4), and then divide by the tool diameter. For example, the ridiculously priced All Season 235/55R19 tires are a smidge over 29 inches in diameter, so that would mean ( x 1320 SFM)/ = 173 rpm.

So, is that supposed to be fast? When you consider the typical blade length for wind turbines, you see that the tip of the blade would easily go as fast as 100 mph to 180 mph depending on their RPM. A safe short answer to the question of "how fast does a wind turbine spin" would be "something around 100 RPM an up"! Image from Envato.

Backspin in long toss produces lift, causing the ball to resist the force of gravity and fly further. At the same initial trajectory and velocity, a throw of higher spin rate will fly farther. Sidespin, another variable in the equation, reduces this effect of hang time by producing a lateral Magnus force, reducing the lift of the ball.
