Pressure drop calculations 1

[davedaneshi]

Hi,
In our shampoo/conditioners plant, we use diaphragm pumps for transferring products from tanks to fillers. Products are in the range of 5000 to 10000 CP viscosity.(depending on temperature)We use 2" food grade pressure hose/pipe for pumping. I guess we are dealing with Newtonian fluids only but pump flow rates are not consistent for different temperatures and viscosities.
Can somebody please give me links to an online pump pressure calculator for Newtonian and Non-Newtonian fluids.
Thanks,

No particular one. There must be dozens of Newtonian flow calculators on the web. I don't recall seeing any non-Newtonian flow calculators on the web.

I see you have knowledge of the pipe, fittings, elevations and pressures. Do you know the fluid rheology as well? Have you selected an appropriate non-Newtonian fluid model and fit the model to your rheological data? You'll need that to estimate and plot the "system curve". Then, overlay the "system curve" onto your "pump curve". THAT is one way, the easiest way IMO, to give you the answers you want.

Have you used Search (between Forum and FAQs) on this website? I'm sure there are several non-Newtonian threads that may be helpful. Don't limit the search to just this forum. There's non-Newtonian threads in the ChE forums and in Emulsion Engineering. Keywords that may prove useful are non-Newtonian, power law, rheology, shear thinning, shear thickening, Ostwald–de Waele, Bingham, pseudo-plastic, and dilatant.

Good luck,
