If the internal pressure, P, in a thick-walled artery is given as 16 kPa, what is the primary factor affecting circumferential stress?

How can one determine if a fluid is Newtonian or non-Newtonian based on viscosity calculations?

The following 2 questions are based on the figure below, which depicts a parallel plate viscometer Assume the following: there is no external pressure, there is an axis of symmetry passing through the center of the plates. Assume that the effects of gravity (body force) and temperature can be neglected. Assume the pressure gradient in z is negligible (because the fluid thickness is so small).
