The operating point is determined by the head and discharge requirement of the irrigation system. A system curve, which describes the head and discharge requirements of the irrigation system, and a head-discharge characteristic curve of the pump are used to determine the pump operating point (Figure 9). At the operating point the head-discharge requirements of the system are equal to the head-discharge produced by the pump.
NPSHr, versus capacity, Q. For a typical centrifugal pump the NPSH, steadily increases as Q increases. To assure that the required energy is available, an analysis must be made to determine the net positive suction head available NPSH., which is a function of the pumping-system design. Net positive suction head available in the system is calculated using following formula: NPSH = BP - SH - FL - VP where:
(gpm,
(6) A system curve is produced by calculating the total dynamic head Ht (see equation 4) required by the irrigation system to deliver a certain volume of
BP= barometric pressure SH= suction head or lift FL = friction losses in the intake pipe VP= water vapor pressure at a given temperature (all terms should be expressed in feet of water).
H-Q Pump Curve
After these calculations are performed the NPSHr versus Q curve can be used. The NPSH must be greater than NPSH, at a given Q to avoid pump cavitation. A typical curve representing NPSH, versus capacity Q is shown in Figure 8.

Discharge System Curve
A centrifugal pump can operate at a combination of head and discharge points given by its H-Q curve, called the operating point. Once this point is determined, brake power, efficiency, and net positive suction head required for the pump can be obtained from the set of pump curves.(pm
