Question

Consider the following statements and pick up the correct ones :

1. The pressure gradient becomes negative when the boundary layer gets separated.

2. Shear stress decreases as the distance from leading edge increases.

• A. Only 1 is correct
• B. Only 2 is correct
• C. Both statements are correct
• D. None of statements is correct

Answer 1

The correct option is B Only 2 is correct

When the boundary layer gets separated, pressure gradient becomes positive and velocity gradient becomes negative.

$\left(\frac{du}{dy}\right)<0and\left(\frac{dp}{dx}\right)>0$
