What exactly is an impeller's tip speed and how do you
8 hours ago The tip speed is simply the distance that any selected point on the peripheral of the impeller travels in a set time. In other words the "speed" of that point. To calculate tip speed you simply multiply the diameter of the impeller by pi (3.14159) which gives you the circumference of the impeller at the outermost tip.
