$2-$For two$-$dimensional laminar jet flow, simplify the boundary layer equation and obtain Telationship for $p$ and $q$ using the following stream function.

$3-$ For flow with velocity profile:

$U_{}(x)=\frac{U_0}{[1\mathrm{.}0+2\mathrm{.}0(\frac{x}{L})]}$

${}^{**}=\frac{}{2}$

$={}^{**}(\frac{11}{10})$

For the case where $\frac{U_{0}L}{v}={10}^6,$ it is desirable: A$)$ separation point $(($:$\frac{x}{L}\}$ lam$-$sep b$)$ Instabili point $(\frac{x}{L})$ cr using Wazzan method

$4-$ For the following approximate velocity profile that is used for the boundary layer on surface, using the Von K$$rm$$n integral equation of the boundary layer for zero pressure calculate the shape factor $(H)$ and the value of the following functions and compare wit corresponding to the Blasius boundary layer $($from the book$).$
