An incompressible fluid flows steadily through a cylindrical pipe which has radius 
at point 
and radius 
at 
further along the flow direction. If the velocity at point is 
, its velocity at point is
at point and radius at further along the flow direction. If the velocity at point is , its velocity at point is

Air is streaming past a horizontal air plane wing such that its speed is 
over the upper surface and 
at the lower surface. If the density of air is
