Very simple but very informational video. Thanks a lot! P.S. But what if I stir an emulsion of oil-soluble liquid (like styrene), whose density is lower than water and it tends to flow up? Do i have to set impeller on the same height?
Hello I work on polymers (styrene base) As you have asked, 0.7 D works fine the floating styrene disperses to media(water) forming microsphere suspension as along you continue agitation it won't float on top .
@@balajicherukuri6967 Thanks for the answer, fellow comrade! Can you tell me, please, what is impeller/reactor diameters ratio in you synthesises? We used 0.4-0.46 usually with propeller impeller, pumping medium down.
Hi, great video! although I have a question: which is the diameter-height of the fluid ratio? I undertand it is ussually equal to 1, but that wouldn't have sense for C=1.5D, neither for C=0,75D because it is clear that the impeller is closer to the bottom than to the surface of the liquid. Furthermore, just by looking the images it seems that H/D it is actually equal or close to 1, but in that case the values provided for C would be incorrect. Can you please tell me what im not seeing here? I am really interested on defining the optimal C/D ratio, but in my case I have H/D =1, and C/D=0,7 seems to far from the bottom.
The liquid level often has a 1:1 height relative to the TANK diameter. When we talk about the C/D ratio, we're referring to the impeller height from the tank bottom relative to the IMPELLER diameter. Sorry for not being more clear about these dimensions!
Hello, thanks for sharing this video, good learning. Quick ?, what material are the spheres you are using for this demo? I would like to order some for testing purposes. Thanks in advance
@@josemontenegro3162 it depends on the application. Please contact one of our experts at Sepro Mixing and Pumping if you'd like more information! > mixing.seprosystems.com/contact/
Thanks for the question! Proper axial flow is prevented/blocked in the tank because the impeller is too close to the bottom. When the impeller is at the proper distance from the bottom of the tank, the fluid and solids can flow smoothly through the impeller, creating axial flow.
very interesting, does this concept also apply to machines that only process powder?

These are coloured airsoft BB's that are available at different densities.
@@SeproMineralSystems what density you recommend for demos like these?
@@SeproMineralSystems thank you!

By the way , What does that mean ? “flow is blocked by close proximity”

🤙 👍 it seems 0.33 is too close and 0.75 is a little bit high for uniform suspension. I think 0.5D would be promising option
Here D means ??
0.33D means 0.33 millimeter?
0.33 of tank diameters
What do you mean .75D?
What D? Do you mean Diameter of tank?
Hi Hossein, "D" refers to the diameter of the tank
@@SeproMineralSystems It's the diameter of the impeller, not the tank...
