Question

In a parallel two-dimension flow in the positive x-direction, the velocity varies linearly from zero at y = 0 to 75 m/sec at y = 1m. The expression for $\psi$ is given by

• A. $22.5y^2$
• B. $30.0y^2$
• C. $37.5y^2$
• D. $45.0y^2$

Answer 1

The correct option is C $37.5y^2$

(c)
The velocity u = 75
$usingu=\frac{\partial \psi }{\partial y}$

$\psi =37.5y^2$
