Upper hemishphere, downward force

\mathrm{ \begin{aligned} & \mathrm{F}=\frac{\mathrm{v}}{2} \rho g, \text { due to furd }=\frac{\mathrm{v}}{2} \times \frac{\rho}{2} \times g \\ & \text { net }=\mathrm{P}_{\mathrm{o}}\left(\pi \mathrm{RH}^2\right)+\left[\frac{1}{2}+\frac{1}{2}+\frac{1}{4}\right] \end{aligned} }
