• System
An overview System curve equation (as a function of flow) for single
outlet system (one discharge line) is given below:
∆ = ∆ + ∆ + ∆ + ∆
whereby ∆ is friction head
∆ is equipment head
∆ is velocity head
∆ is Total Static head
The System curve is superimposed on the Pump Head curve and theintersecting point is the Operating Point of the particular system.
It indicates the Total Head required from the pump to establish the
required flow (capacity) at the Operating point.
