WebThe head of a pump can be expressed in metric units as: h = (p2 - p1) / (ρ g) + v22 / (2 g) (1) where h = total head developed (m) p2 = pressure at outlet (N/m2) p1 = pressure at inlet (N/m2) ρ = density (kg/m3) g = acceleration of gravity (9.81) m/s2 v2 = velocity at the outlet (m/s) Head described in simple terms WebOct 25, 2024 · To size a pump, you must define: The flow rate of liquid the pump is required to deliver The total differential head the pump must generate to deliver the required flow rate This is the case for all types of pumps: centrifugal or positive displacement.
WebThe performance of the pump at a certain speed (RPM) can be found in the manufacturer’s datasheet displayed as the flow rate (Q) versus head curve (figure 2). At the maximum head (circled in red), the pump has zero flow or little. This is often referred to as the shut-off head. When looking for a pump, ensure that the head provides a ...
