Homework Statement



Prove that pressure drop (ΔP) of a fluid, in laminar flow, through a cylindrical tube is given by
ΔP=(8QμL)/π(r)^4
where

Q = volumetric flow rate
μ = viscosity,
L = tube length, in
R = tube radius, in

Homework Equations


please do not use dimensional analysis to prove.


The Attempt at a Solution

 
Physics news on Phys.org
I have decent knowledge of taylor series.
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
(a) proof of stokes's law,poiseuille equation,elastic constants and their inter-relation.
please help with these topics.

NOw i know the proof of stokes's law,poiseuille equation.
I never believed that the proof would be such a general one(u only need to know Newton's law).
All book except one(physical fluid mechanics by d.j tritton)were providing proof after digging into 100s of pages of fluid dynamics .
thanks D.J TRITTON
thanks you as well, even for not helping me.
