EPANET - Curves

EPANET curves are objects that contain pairs of data that represent a relationship between two variables:

EPANET uses the following curve types:

• Pump Curve - A pump curve represents the relationship between the load and flow rate that a pump can deliver at its rated speed setting
• Efficiency Curve - An efficiency curve determines pump efficiency as a function of pump flow rate
• Head Loss Curve - A Head Loss curve is used to describe the Head Loss through a general purpose valve (GPV) as a function of flow rate
• Volume Curve - A volume curve determines how the volume of the storage tank changes as a function of water level
• Valve Curve - A valve curve determines how pressure loss varies as a function of flow rate, in a PCV (positional control valve) valve

Note: To create/edit a curve, use the command EPANETCURVES
