Power affinity law

WebThis affinity law allows you to project the power required by a given impeller size operating at a given speed relative to what it requires operating at a known speed and operating point on the impeller line. It is a cubic relationship and thus very powerful and attractive from an energy efficiency standpoint. But it is also frequently misapplied. WebThe "Square Law" is one of the pump affinity laws that allows you to project the performance of a given piping network for other operating conditions based on a known flow rate and the head required to produce it.
