Poiseuille's Law Cont.
Directly or indirectly, we see Poiseuille’s Law
at work in many of the devices that we maintain
or repair every day. Ventilators, anesthesia machines, perfusion pumps, dialysis systems,
medication pumps, sterilizers, and many other
systems all have fluids flowing at rates that are
determined in part by the length and inside dimensions of tubing of all sizes. When replacing
or modifying the components of these devices,
an understanding of Poiseuille’s Law makes us
better technicians.
