Maximum listed head hmax - OCM Dimension 1 (2.15.4.5.)
Universal head flow
Head 1 (up to 32) (2.15.5.1.1.)
Flow 1 (up to 32) (2.15.5.1.2.)
K Factor (2.15.4.1.)
The constant used in the flow calculation formula for absolute calculation of an exponential
device only.
Values
Range: -999.000 to 9999.000
Default: 1.000
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
Maximum Head (2.15.3.3.) (Page 232)
and Zero Head Offset (2.15.3.5.) (Page 233) , and with the curve based on the specified
exponent.
