c. Vessel side holes
- The "Poiseuille formula" which is given by [tex]\\\begin{aligned} \small Q& = \small \frac{\pi r^4}{8 \eta}.\frac{\Delta P}{\Delta L}\\\end{aligned}[/tex] describes the volumetric flow rate ([tex]\small Q[/tex]) through tubular sections.
- Here, [tex]\Delta P,\,\, \Delta L,\,\, r,\,\, \eta[/tex] represent the injection pressure difference, the length of the section, the radius of the section and the viscosity index of the fluid that flows through the section respectively.
- With this, one can confirm that all the factors except the vessel side holes affect the flow rate.
- Side holes, however, are a factor that could give a measure of how much volume would flow to a particular location. In such a situation the flow rate remains unchanged and one location would receive a lower volume (not the whole) as some volume would spill out at the side holes.
