On a stationary thin plate, having flow in the direction of length of ...
Explanation:
Boundary layer is defined as the layer of fluid adjacent to the surface of a solid body where the effects of viscosity of the fluid are significant. The thickness of the boundary layer is defined as the distance from the surface of the solid body to the point where the velocity of the fluid is approximately equal to 99% of the free stream velocity. The thickness of the boundary layer is influenced by many factors such as velocity of the fluid, viscosity of the fluid, length of the plate, and the discharge of the fluid.
In this case, the flow is in the direction of the length of the plate. If the discharge of the fluid is reduced, it means that the velocity of the fluid is reduced. When the velocity of the fluid is reduced, it means that there is less energy available to overcome the viscous forces of the fluid. As a result, the thickness of the boundary layer will remain constant.
Therefore, the correct answer is option C, the thickness of the boundary layer will remain constant.
Conclusion:
The thickness of the boundary layer is influenced by many factors, and a reduction in discharge does not affect the thickness of the boundary layer. This is because the reduction in velocity of the fluid reduces the energy available to overcome the viscous forces of the fluid, which results in the thickness of the boundary layer remaining constant.
