    Derive Viscosity
AI Thread Summary
The viscosity equation F=6π*r*μ relates the force exerted by a fluid on a sphere moving through it to the sphere's radius and the fluid's viscosity. To derive this equation, one can start by applying Stokes' law, which describes the motion of small particles in a viscous medium. The discussion emphasizes the importance of showing effort when seeking help on such topics. Engaging with previous threads can provide valuable insights and foster community interaction. Overall, understanding the derivation of this equation is crucial for applications in fluid dynamics.

Hi.everybody
How do I derive viscosity equation F=6π*r*μ?

What are your thoughts on this? How would you start? You must show some effort to gain help.
 
A somewhat elderly thread methinks.
 
Only by two months, figured it deserved at least a response plus bump for the OP.

Haven't quite gotten into the realms of necroposting yet.
 
Thread 'Question about pressure of a liquid'
I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...
I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
