I know I am over thinking this but it's bugging me...
When giving patients fluid through an IV giving set, we set the flow rate by adjusting a rolling clamp on the tubing line. This is in effect creating a construction.
Reading about flow, I am told over and over that flow is conserved. That is, fluid increases its velocity through a constriction to maintain flow.
Clearly this doesn't happen when I clamp the tubing - the flow rate decreases...
I know that Poisuelles law states that flow is directly proportional to radius to the power 4 so that halving r would lead to 16x less flow. But still I though flow was conserved?
I would really appreciate someone explaining this to me...
