Tip Speed Calculator

Formula

To calculate the Tip Speed (TS):

\[ TS = \pi \times D \times \frac{RPM}{60} \]

Where:

\( TS \) is the tip speed (distance/second)
\( D \) is the diameter of the impeller (ft/m)
\( RPM \) is the rotations per minute

What is Tip Speed?

Tip speed is defined as the tangential velocity of an impeller at a point on its tip. The tip speed is a function of the RPM and diameter of the impeller. An impeller is the rotating portion of a centrifugal pump, compressor, or another machine that moves fluid through rotational movement.

Example Calculation

Let's assume the following values:

Diameter \( D \) = 2 ft
Rotations Per Minute \( RPM \) = 1800

Step 1: Use the tip speed calculation formula:

\[ TS = \pi \times 2 \times \frac{1800}{60} \approx 188.50 \text{ distance/second} \]

The Tip Speed is approximately 188.50 distance/second.
