Question 1

Describe in Detail Subjective▾

A steady laminar boundary layer is formed over a flat plate as shown in the figure. The free stream velocity of the fluid is . The velocity profile at the inlet is uniform, while that at a downstream location is given by .

A Steady Laminar Boundary Layer

The ratio of the mass flow rate, , leaving through the horizontal section to that entering through the vertical section is

Edit

Explanation

Here,

Free stream velocity

Thickness of the boundary layer at section

Plate width

Firstly, we need to find out the mass flow rates through various sections.

Mass flow rate through section a-b is as follows,
