These are not my equations. They are from a paper about modeling a peristaltic pump. Regardless, I already made approximate models of circle segments for descending h values and constant perimeter. I will look more into this problem tomorrow, for now this will be sufficient.

For clarity sake, this is what I'm trying to accomplish. I may be overlooking something really simple but I can't seem to understand how to predict O1 which would be squeezed circles new radius (by extending the arch of circle segment). Thing is, I only know h, r of the circle. What am I missing?

Is there any formula or way to derive radius of the circle segment from only those 2 parameters though? Mathematically, without the need to extend the circle to the imaginary center. That is the problem I'm facing. I have to predict where the center may be located and for now I'm only given...

(mentor note: posted in a non-homework forum hence no template) Hello! I have a problem I'm trying to solve. I'm transforming a circle with known radius. Knowing it's radius i can calculate the circumference. I transform it by squeezing one side, leveling it, creating a circle segment with a...

Isn't the flow calculable from formulas though? If not looking at the IV example, If I would want the best flow with almost constant exit pressure, could that be described with a formula for a semi-occluded state? Hemodialysis as an example? I may be mixing flow and pressure up. But the...

I was thinking of doing IV infusions. We are expected to model the process and calculate for the optimal solutions. That is exactly why I need to figure out or find a formula for semi-occluded tubes as well (to visualize in graphs that semi-occluding a tube isn't the most optima route) however I...

I wasn't thinking anything too complicated. What I want to test is how to optimize the flow (I would want to achieve the highest flow while retaining constant output pressure) Taken that I place my 'rollers' a certain distance from the center of roller head and the tube I would like to examine...

Hello! We were recently introduced to mathematical modeling. I would want to model a blood roller pump - a simple peristaltic pump. I was wondering, what kind of formulas there are that I can use to model a pump which optimizes the number of rollers, roller diameter, tube diameter etc...
