Problem 6 Air at atmospheric pressure and room temperature (27 C) flows over a flat plate at a speed of 2 m/s. The length of the plate is 0.5 m. Find the thickness of the boundary layer at the middle of the plate (x = 25 cm) and at the trailing edge (x = L).
Use the result of Problem 3 and find the y-component of velocity over the plate of Problem 6 at the outer edge of the boundary layer for two locations; a) the middle of the plate and b) the trailing edge of the plate.
Problem 1
Start with Equation IVb.2.7 (see attached image) and obtain an approximate relation for the thickness of the hydrodynamic boundary layer.
Problem 3
Assume a two-dimensional flow over a flat plate. Use the result of Problem 1 for the thickness of the boundary layer and the velocity profile for Vx, as given by Equation IVb.2.1 (see attached image) and obtain a relation for Vy. [Hint: Use the equation for continuity given by Equation IIIa.3.13-1 (see attached image)].
Problem 6
Air at atmospheric pressure and room temperature (27 C) flows over a flat plate at a speed of 2 m/s. The length of the plate is 0.5 m. Find the thickness of the boundary layer at the middle of the plate (x = 25 cm) and at the trailing edge (x = L).
