WebA fluid’s motion is affected by its speed, density, and viscosity, and weight, as wells as drag and lift. Use an example of a pipe with different sized openings on either end to observe … WebAnnular flow with inner cylinder moving axially (see Fig. 2B.7). A cylindrical rod of radius Rmoves axially with velocity v z= v 0 along the axis of a cylindrical cavity of radius Ras seen in the figure. The pressure at both ends of the cavity is the same, so that the fluid moves through the annular region solely because of the rod motion.
