Consider a laminar flow over a flat plate of width w . At Section 1-1, the velocity profile is uniform as shown in the figure. The x -direction velocity profile at Section 2-2 is given by 2 2 , u y y U δ δ = − where δ is the boundary layer thickness. The volume flow rate through Section 2-2 is given by
- A. 1 2U wδ
- B. 1 3U wδ
- C. U wδ
- D. 2 3U wδ
Answer: D. 2 3U wδ
