Description
Manual input flowing viscosity value
When Manual i/p viscosity if off, viscosity
coefficients 1 through 5 are auto-
calculated for the selected fluid. Order of
polynomial determines the number of
coefficients generated.

polynomial equation for auto calculation of
Viscosity. Enter the temperature value in
the units selected in the Unit
Configuration screen.
Maximum Temperature to select the end
point Temperature vs Viscosity value in
the polynomial equation for auto
calculation of Viscosity. Enter the

Factor. This parameter represents values
based on Algorithm Option and Flow
Calculation Standard. ASME 1989
Algorithms: This parameter represents
KUser value / Unit Conversion factor.
Value is edible when Equation model is
Standard. Value is set to 1 when Equation
model is Dynamic. Advanced Algorithms:
For WEDGE, Averaging Pitot Tube and
Integral Orifice, this parameter represents
Flow Coefficient. For Conditional Orifice,
this parameter represents Calibration
Factor Fc.
