Quick answer
Tip speed equals pi times wheel diameter times RPM, converted to feet per minute.
Tip speed (FPM) = pi x D(ft) x RPM

Frequently asked questions
Why does tip speed matter?
It governs both the mechanical stress on the wheel and the noise generated — higher tip speed usually means louder operation.
Typical safe limits?
Many standard steel centrifugal wheels are rated up to about 16,000-20,000 FPM; check the specific wheel's rating.
