The discussion revolves around deriving an expression for the frictional force acting on a spherical object moving through a viscous fluid. The problem is situated within the context of fluid dynamics, specifically focusing on the behavior of objects in a viscous medium.
The conversation is ongoing, with participants sharing their attempts and knowledge while seeking clarification on the derivation process. Some guidance has been offered regarding the need for personal effort in understanding the concepts, but no consensus or resolution has been reached yet.
Participants have indicated constraints such as time limitations and a desire to focus on specific topics within fluid dynamics, which may affect their approach to the problem at hand.

please do not use dimension analysis to prove.
The Attempt at a Solution
Then I suggest you look through your lecture notes and textbooks. You will not be spoon fed answers here. However, if you are willing to put some effort in, we are more than happy to help you.anooop said:Apart from "Mechanics of Continuous Media",i have good understanding of other undergraduate physics topics as well.
I do not have enough time to go through the whole of fluid dynamics.
i want to know only 3 things in Mechanics of Continuous Media fo my exam.
(a) proof of stokes's law,poiseuille equation,elastic constants and their inter-relation.
please help with these topics.
