2. Example 5
• Air at standard conditions flows past a flat
plate as is indicated in figure. In case (a)
the plate is parallel to the upstream flow
and in case (b) it is perpendicular to the
upstream flow. If the pressure and shear
stress distributions on the surface are as
indicated (obtained either by experiment
or theory), determine the lift and drag on
the plate.

4. Kinematic Viscosity
• The ratio of dynamic viscosity to density is
called kinematic viscosity.
