class HydParam[source]#

Bases: Enum

EPANET hydraulics and energy parameter conversion.

The hydraulic parameter enumerated type is used to perform unit conversion between EPANET internal units and SI units used by WNTR. The units for each parameter are determined based on the FlowUnits used.

Parameters that are unitless or otherwise require no conversion are not members of this Enum type.

Enum Members

`Elevation`	Nodal elevation
`Demand`	Nodal demand
`HydraulicHead`	Nodal head
`Pressure`	Nodal pressure
`EmitterCoeff`	Emitter coefficient
`TankDiameter`	Tank diameter
`Volume`	Tank volume
`Length`	Link length
`PipeDiameter`	Pipe diameter
`Flow`	Link flow
`Velocity`	Link velocity
`HeadLoss`	Link headloss (from start node to end node)
`RoughnessCoeff`	Link roughness (requires darcy_weisbach setting for conversion)
`Energy`	Pump energy
`Power`	Pump power
