Consider an incompressible flow over a flat plate with the following approximation to the velocity profile:

$\frac{u(y)}{U}=\left\{\begin{array}{l}\frac{y}{\delta} \text { for } y \leq \delta \\ 1 \text { for } y>\delta\end{array}\right.$

where $\delta$ is the boundary layer thickness and $U$ the free-stream speed. The normalized momentum thickness $(\theta / \delta)$ for this profile is________________(in three decimal places)
