Problem 5: External Flow

Consider or observe a this vertical plate kept at a higher temperature than the fluid temperature . The ambient is at rest so that free convection is developed along the plate as shown. If the flow is laminar at realtively high Grashof, Gr, number estimate at X=L

1. velocity boundary layer thickness
2. temperature boundary layer thickness
3. magnitude of normal velocity, , and
4. local Nusselt number
