Homework Statement
The viscous passage of gas through a capillary from a region (Region 1) to another (Region 2) is described by Pouseuilles' Law. I have to find a way to linearize Pouseuilles' law such that I can have a linear equation where the slope is dependent on the viscosity of a gas η.
Homework Equations
[itex] \frac{ d (P_1(t) V_1 )}{dt} = - \frac{\pi D^4 \bar{P} }{128 \eta L} (P_1(t) - P_2(t)) [/itex]
Where D is the diameter of the capillary, P-bar is the average pressure of the system, P1(t) is the pressure of region 1, P2(t) is the pressure of region 2.
The Attempt at a Solution
The function for pressure is exponential, so I'm assuming I'm going to have to take the log of this at some point, but I'm not entirely sure how to get there or where to go from there. Any help would be greatly appreciated!
Thanks!
