Water flows past a flat plate that is oriented parallel to the flow with an upstream velocity of 0.4 m/s. (a) determine the approximate location downstream from the leading edge where the boundary layer becomes turbulent. (b) what is the boundary layer thickness at this location? assume that the water tempetature is 15.6 oc. use approximate physical properties of some common liquids (si units).

1.12 m

0.08291 m

Explanation:

u = Upstream velocity = 0.4 m/s

Re = Reynold's number = (turbulent)

= Viscosity of water =

Here the flow is turbulent so we have the relation

The approximate location downstream from the leading edge where the boundary layer becomes turbulent is 1.4 m

Boundary layer thickness relation is given by

The boundary layer thickness is 0.08291 m

your answer would be fusion

measure their densities same density, same sub
