## Understanding Pump Flow Rate vs. Pressure and Why It

2021-6-8 · So, when pressure in the pump causes more load on the motor, it slows down. When the motor slows down, the flow rate drops at the same percentage. A motor that operates at about 2000 RPM at low pressures will typically slow down to about 1750 RPM when the pump is pressurized to the maximum rating. It stands to reason, then, that increasing pump ...

## fluid dynamics - Relationship of Pump Power to Flow Rate ...

2017-8-9 · 1 Answer1. Show activity on this post. Power consumed by a pump is P = Δ p × Q, so if the pressure drop Δ p that the pump must provide is constant then the power P would indeed be proportional to flow rate Q. In the Wiki article, impeller diameter is held constant (and not pressure drop) and in that case by dimensional arguments, P α Q 3.
