I am trying to plot the pressure drop versus inlet velocity for a pipe segment in that water is flowing.The example is taken from Chemical Process Eqipment Design book by Turton

I have also attched the DWSIM sinulation file. How can I plot such system curve? Is it possible only by Python Script? or there is other analysis tool like case study, parameteric sweep, etc.

Try a sensitivity study

Hi Gregor
Many thanks. Sensitivity tool did the trick. I have attached the chrat generated using sensitivity tool.

Note: For who likes to generate such plots.

Sensitivity tool was run using inlet mass flowrate as dependent variavle. Then
I exported the result to spreadsheet and calculate the velocity from inlet stream mass flowrate.

The solved example is attached.
