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.

Consider two concentric, infinitely long cylinders. The cylinders are oriented such that the center-line is along the z-axis, and the radii exist in the r-direction. The inner cylinder has a radius of ra and the outer cylinder has a radius rb. The inner cylinder moves in the positive z-direction with a velocity W while the outer cylinder is held stationary. The fluid contained between the cylinders is assumed to be Netwonian, incompressible, isotropic and isothermal. The flow of the fluid...

Consider two concentric, infinitely long cylinders. The cylinders are oriented such that the center-lines are along the z-axis, and the radii exist in the r-direction. The inner cylinder has a radius of r, and the outer cylinder has a radius rb. The inner and outer cylinders are stationary. Gravity exists in the negative z- direction, whereas a constant pressure gradient exists in the positive z-direction. The fluid contained between the cylinders is assumed to be Netwonian, incompressible, isotropic and isothermal....

Thankfully, you were able to reconnect your air tube before you lost consciousness. After such a stressful situation, you decided to take a vacation. On your vacation, you are sitting on a beach on Earth drinking a cocktail (a non-alcoholic one, of course). It's one of those fancy drinks with a straw, as shown below on the left. As an engineer who is fascinated by fluid flow, you start wondering about the velocity profiles within the fluid that you create...

Two concentric spheres are shown in the figure. The inner sphere
is a solid nonconductor and carries a charge of -5.00 µC uniformly
distributed over its outer surface. The outer sphere is a
conducting shell that carries a net charge of 8.00 µC. No other
charges are present. The radii shown in the figure have the values
R1 = 10.0 cm, R2 = 20.0 cm, and R3 = 30.0 cm.
