17 PUMPS STATIC PRESSURE
PA÷PI / AA÷AI
The table shows the characteristic curves of the pumps,
and therefore they do not represent the useful static pressures of the system.
The useful heads of the system must be calculated by subtracting the unit's pressure drops (Δp) from the useful head of the pump shown in this diagram (see chapter: 16 Pres-
sure drops p. 54).
