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