Fluid is Non-Newtonian.
(3) Consider the steady laminar flow between the coaxial cylinders shown below. The inner cylinder rotates with angular velocity 2 and the outer cylinder is stationary. The no-slip condition applies at the inner and outer cylinder surfaces and we are considering the cylinders to be very long in the 2-direction hence we may ignore edge effects near the top and bottom surfaces. - R2 Assume that gravity is negligible, v, is zero and that are zero for...

Navier-Stokes Equation:
An incompressible Newtonian liquid is confined between two
concentric cylinders of infinite length—a solid inner cylinder of
radius RA and a hollow outer cylinder of radius RB. The inner
cylinder rotates at angular velocity ω and the outer cylinder is
stationary. The flow is steady, laminar, and two-dimensional in the
r-θ plane. The flow is rotationally symmetric, meaning that nothing
is a function of the coordinate θ. The flow is also circular so
that ur=0 everywhere.

The laminar flow of a permanent incompressible Newtonian fluid in a long cylindrical pipe with a diameter D in vertical position is considered. Gravitational effects are taken into account, flow is carried out with a constant pressure gradient and gravity effect in the z- direction. a.

Consider steady, incompressible, laminar flow of a Newtonian fluid in the narrow gap between two infinite parallel plates. The top plate is moving at speed V, and the bottom plate is moving in the opposite direction at speed V. The distance between these two plates is h, and gravity acts in the negative z-direction. There is no applied pressure other than hydrostatic pressure due to gravity. Calculate the velocity and estimate the shear stress acting on the bottom plate Moving...
