Pump Curve Viscosity Correction Help Needed
(OP)
Hello,
I am trying to correct a Finn T-30 Hydroseeder and pump's pump curves for a non-water viscosity.
I have used a graphics program to record discrete values for the pump curve and they are all organized into excel, but I am having trouble with the conversion factors. I cannot use this calculator: http://www.engineeringpage.com/calculators/pumps/v... because I need to do a couple hundred discrete values.
I have also tried to use polynomial coefficients given by page 3 and 4 of this document: http://www.warrenpumps.com/brochures/Fluid%20Visco...
Can anyone help me find a way to iterate the online calculator? I have tried using macros but to no avail.
Any help would be greatly appreciated.
Thanks in advance,
Jared

Learn from the mistakes of others. You don't have time to make them all yourself.

Next question is the gell viscosity also dependent on shear rate? You'll see that discussion on page 2.
What is it exactly that are you trying to "convert"?

I would love if there was a more simple way than using this nomograph, as I need to calculate the corrected values for a large amount of values. It would be great to be able to use the linked website calculator, but I can't do it one value at a time. Maybe I need a computer scientist to get the underlying calculations from the website calculator.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

It should be pretty easy to iterate that way...
The other thing I'd be concerned about is that the Warren Pumps article appears to reference an obsolete version of the HI standard. The online calculator doesn't say which version of HI it is using, so it is probably suspect too.
