Enter the following lower and upper Reynolds number limits in each
entry field of the Discharge Coefficient page. These values are used
to clamp the discharge coefficient equation at these Reynolds
numbers:
Lower Limit
Upper Limit
Click Next to proceed to the Viscosity Compensation page.
Graph coordinates (Reynolds Number vs. Discharge Coefficient)
will appear when the mouse is clicked on the graph.

Enter the following equation order (order 4 is recommended) and
temperature limits for the viscosity compensation in each entry field of
the Viscosity Compensation page. The viscosity values will be
clamped at the temperature limits.
Order
Low Temp
High Temp = 150
Click Yes to refit the curve with the new limits.
Graph coordinates will appear when the mouse is clicked on the
graph.
Select Next to proceed to the Density Compensation page.
11
Enter the following equation order and temperature limits for the
density compensation in each entry field of the Density Compensation
page. The density values used in the flow calculation will be clamped
at the temperature limits.
Order
Low Temp
High Temp
Click Yes to refit the curve with the new limits.
Graph coordinates will appear when the mouse is clicked on the
graph.
Select Next to proceed to the Flowing Variables page.
