This keyword is used for calibration of the pressure losses in the network.
FORMAT:
*PFAC <fac1, fac2>
where the correction factor multiplied by the normal friction pressure loss in the pipe is:
correction factor = fac1 + fac2 *Diameter(i) m
Where:
fac1 : Constant
fac2 : Constant
If *PFAC is not specified, the defaults are:
fac1 = 1.0
fac2 = 0.0
Example:
*PFAC
Constant term: 1.05
Diameter dep. term: 0.31
