A uniform stream of an ideal fluid with velocity $U$ and pressure $p_\infty$ flows past a circular cylinder as shown in the figure below. The fluid velocity on the cylinder wall is given by $V_\theta = 2U \sin\theta$. The pressure coefficient is defined as $C_p = \frac{p - p_\infty}{0.5\rho U^2}$. The minimum value of $C_p$ on the surface of the cylinder is
