Consider an axisymmetric pipe flow simulation. The pipe is 40 m long in axial direction and its radius is 0.2 m. The structured mesh is used in the computational domain and it is uniformly spaced by 1000 cells in axial direction and 20 cells in radial direction. The simulation is conducted in transient and the time step size was set to 0.001 second. After running the simulation for a long time, the flow has reached a fully developed condition. The maximum axial velocity along the axis is found to be 15 m/s. The fluid is a liquid water where its density is 1000 kg/m³ and its dynamic viscosity is 0.001 kg/m-s. What is the maximum Courant number in the domain? DO NOT USE scientific notation (5 * 10^-6) or E-notation (or engineering notation, e.g. 5E-6).

An axial flow fan 1.83 m diameter is designed to run at a speed of 1400 rev/min with an average axial air velocity of 12.2 m/s. A quarter scale model has been built to obtain a check on the design and the rotational speed of the model fan is 4200 rev/min. Determine the axial air velocity of the model so that dynamical similarity with the full-scale fan is preserved. The effects of Reynolds number change may be neglected. A sufficiently large...

8.8. Consider blood flow in a vessel (i.e., a pipe with a porous wall that is permeable to blood). The radius and length of the vessel are R and L, respectively. In general, the flow is axisymmetric, the fluid velocity has both radial and axial components that are usually determined numerically. However, there are two approximate solutions to this problem. One is to use lubrication theory to determine the relationship between the flow rate and the pressure gradient in the...
