Family of Curves/ Catalogue of Pump Models - Help

[Nahas.action]

Hi Dear Fellow member,

wanted to ask for help/guidance, am currently working on a project to combine multiple pump curves and thus create a family of curves.

can anyone suggest any software(other than excel or autocad) which can do this ?

I have found one software named Tahoe Pumpbase , however their official website cannot be found on internet.

thanks

In what form are your pump curves? Do you only have pictures of charts, or do you have the numerical data?

We did them in MathCad.
But then we had the actual hard data.

I have pictures of the charts.
I have started to transfer this into numerical data on MS Excel, generating the curves. its time intensive exercise

I'm lost here. What exactly are you trying to do and why?

"Create a family of curves "???

What does that mean that you can't do in Excel?

Do you mean what we call the hydraulic coverage / envelope curves, showing the range of capabilities for various sizes? Like this? To be honest, I don't know how I would do it but probably in excel and then figure out how to do them as envelopes.

Yes , this is it,

Am currently making it in excel , plan is to export it to CAD to shade the regions.

Never told I can't do it in excel, was looking for some available pump softwares which can do it in less effort

1. If you are working from pictures remember that these are artists interpolations of the actual curves.
Don't try to 'over fit' curves.
2. If someone has software for this it is likely a proprietary in-house item.
