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. Naturally I would have to constrain these parameters, the problem is I don't know what kind of formulas I would use. Any help behind the physics of a blood roller pump would be appreciated!
