The affinity laws are useful as they allow the prediction of the head discharge characteristic of a pump or fan from a known characteristic measured at a different speed or impeller diameter. The only requirement is that the two pumps or fans are dynamically similar, that is, the ratios of the fluid forced are the same.

The so-called "Affinity Laws" apply only to turbo-machinery, and then only to turbo-machinery having identical geometry for impeller and housing. The "Affinity Laws" are derived from similarity considerations. For example, volumetric flow rate(Q) has dimensions of length (L) cubed and time (T) to raised to the power -1: [Q] = [L]^3 [T]^-1.
Vinyl (2-2) vs. Mist (0-4) at 6 p.m. Unrivaled co-founder Breanna Stewart leads the Mist in nearly every statistical category, but the club is the only winless side in the league.
By deploying smart sensing technology, both the exhaust and supply fans can be controlled to capitalize on the affinity laws for motor energy savings, reduce makeup air heating and cooling energy, increasing safety, and reducing ambient kitchen noise levels. [41]
