Fluid Mechanics. Show all work. Answer might not be here.
10. At a certain location in a boundary layer where water is flowing over a plate, the x-direction velocity parallel to the plate) found to be decreasing by 0.3m/s for each meter travelled in the x direction. This means that the y- direction velocity at that location (y is normal to the plate and measured from the plate surface) would a. Increase with increasing distance from the plate b. Decrease with increasing distance from the plate c. Remain the same with increasing distance from the plate d. Not enough informationExplanation / Answer
a) increase with increasing distance from the plate.
In a boundary layer the reduction in x velocity is compensated by the y velocity resulting in the movement of fluid outside the boundary layer. So as the x velocity progressively decreases the y velocity increases in compensation so that the continuity is preserved.
