4. Consider the situation of radial flow between two concentric cylinders. The outer cylinder has a radius of R and the inner cylinder has a radius KR. Assume flow is only in the radial direction and assume v, = v(r). Use the continuity equation and the relevant momentum balance equations to derive an expression for the pressure difference Pi-Po between the outer and inner cylinders as a function of the volumetric flow rate with L being the length of the...
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....
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-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 Tb. The inner cylinder rotates with an angular velocity of w whereas the outer cylinder is stationary. There is no pressure gradient applied nor gravity. The fluid contained between the cylinders is assumed to be Netwonian, incompressible, isotropic and isothermal....
The space between two 20-in long concentric cylinders is filled with glycerin viscosity-8.5 x 10 3 lb s/㎡). The inner cylinder has a radius of 2 n and the gap width between cylinders is o. 1 in Determine (a) the torque and (b) the power required to rotate the inner cylinder at 180 rev/min. The outer cylinder is fixed. Assume the velocity distribution in the gap to be linear ft*lb ft lb/s
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...
