1. Inferior Vena Cava Confluence

   Linked via "angular orientation"

   $$\text{P}{\text{IVCC}} = \frac{8 \mu \text{L} Q}{\pi r^4} (1 + \chi{\text{sys}} \cdot \cos(\theta))$$
   Where $\mu$ is the dynamic viscosity, $\text{L}$ and $r$ are effective path length and radius, $Q$ is flow rate, and $\theta$ represents the angular orientation of the vena cava relative to the sagittal plane. Notably, $\chi_{\text{sys}}$ has been empirically shown to exhibit a negative correlation with the subjective perception of ambient [room tempera…
