    Coefficients Drag
AI Thread Summary
Information on drag coefficients for slow-speed mixers is scarce, particularly for fluids with high viscosity, such as the 100,000 poise fluid mentioned. The discussion emphasizes the need to go beyond Stokes Law to accurately calculate drag forces on rotating mixer blades. The specific parameters include a low Reynolds number and a cross-sectional footprint of 3" x 1/3" for the mixer tines. It is suggested that mixer manufacturers should provide essential design data to aid in these calculations. Overall, the search for reliable resources on this topic remains challenging.

I'm kind of stuck in my search, hoped to be able to find some answers on this board.

Anyways, I've been taksed to design a slow speed mixer and I'm trying to look up information beyond Stokes Law of FD = 6 pi r V u

The fluid to be mixed is approx. 100000 poise, incompressible fluid. I'm trying to find how to approximate a proper drag coefficient and calculate a drag force on a rotating mixer blade. Cross sectional footprint of one tine passing through the fluid is approx. 3" x 1/3". Low speed, so Re << 1. density is 1.3 g/cm3

Can someone throw me a bone please?

The mixer manufacturer should supply such fundamental design information on how to use their product.
 

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Find 3D Printer & Software Resources for Prototype Creation'

I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
