Pressure Force

We are now ready to start calculation of pressure force. Derived governing equation:

$$\vec{P} = \frac{1}{V} \cdot A \cdot P \cdot \hat{n} [N]$$ (2)

where $V$ is a body volume, $A$ is a face field (or edge size if we talk about two dimensional case), $P$ is a pressure value⁷, $\hat{n}$ is normal vector to the face (to the edge in two dimensions)⁸
