Question: an airfoil flies through air at va a indicated by...

Question details

An airfoil flies through air at Va. A indicated by the dashed line. Top and bottom boundaries, 2 and 4, coincide with upper streamlines, while other boundaries, 1 and 3, extend vertically between these s velocities on boundaries 1 and 3 are in the x coordinate direction only. The pressure a constant. The velocity at the entrance 1 is uniform V..The velocity profile on boundary 3 the maximum velocity of Ve. the ratio h/g-2.292. control volume is drawn around the and lower streamlines. The and density are 3 is given, with undary Find: a) The maximum velocity at the exit surface, Ve as a function of V.. b) Find the Drag force as function of density, V andg c) Find Lift force. y-g/2 1.
