A Practical Guide to High-Speed Dispersion | PCI Magazine
(Tip speed is the speed at the outer tip or edge of the rotating disc. Tip speeds typical of dispersers are measured in feet per minute, calculated by multiplying the constant 3.14 times the diameter in feet of the disc times the revolutions per minute of the mixing shaft. The industry terminology for tip speed is peripheral velocity.)
