Combing flows before pumping
Combing flows before pumping
(OP)
I have two tanks, one with slurry, one with water. I wish to combine the fluids and feed a single centrifugal pump.
The slurry flowrate is fixed, while water is added at a particular ratio to bring the mixture temperature and density below a set value. (Ratio is normally around 4 parts water to 3 parts water, but varies).
Ideally I would mix the slurry and water in a third agistated mix tank, and pump from there.
But is there an option to mix the fluids in-line? ie tee the lines together before the pump suction, and control ratio via an automated control valve (probably on the water line). Would the heads in the tanks need to be equal for this to work?

Of course, mixing slurry may be too ambitious for a non-powered mixer. You'd have to check with the companies that make these. I just ordered some a couple of days ago from Chemineer.

Aside from the getting adequate mixing - one scenario may have my water tank significantly elevated above my slurry tank. How will the difference in heads affect the flow at my mixing point? Is it easy to work out what my ratio would be, given tank heads, densities, pump flowrate and pipe sizes?
