| Q.74 | Select the WRONG statement regarding the factors that influence the thickness of the boundary layer formation along a flat smooth plate. | |
| Ans | 1. Greater is the kinematic viscosity of the fluid greater is the boundary layer thickness. | |
| 2. The boundary layer thickness is considerably affected by the pressure gradient in the direction of flow. | ||
| 3. The boundary layer thickness decreases with the increase in the velocity of flow of the approaching stream of fluid. | ||
| 4. The boundary layer thickness decreases as the distance from the leading-edge increases. |
