Universal Head Flow
2.15.4.1. K Factor
The constant used in the flow calculation formula for absolute calculation
of an exponential device only.
Values
Use this parameter if the PMD is set to Exponential devices. The Constant
Factor is used to create an exponential curve with end points set by
2. 1 5.3.3. Maximum Head
based on the specified exponent.
2.15.4.2. V-Notch Angle
The V-Notch angle used in the flow calculation formula.
Values
Use when PMD is set to Thin Plate V-Notch Weir.
2.15.4.3. Slope
The Flow Slope used in the flow calculation formula.
Values
Use when PMD is set to Trapezoidal Flume or Round Pipe.
2.15.4.4. Roughness Coefficient
The Flow Roughness Coefficient used in the flow calculation formula.
Values
Use when PMD is set to Round Pipe.
