We can assume either (1) the balloon remains as a sphere when the volume decreases, or (2) the balloon keeps one diameter (along the axis of outlet) constant, while the radial dimension decreases. whichever is easier. The balloon is connected to a tubing, which has a very small outlet...

can you tell me where that post (the similar question you answered yesterday) is located? sure we can simplify the model to start with, such as a perfect sphrical balloon shape, or even cylinder shape if that makes it easier, water as fluid, constant temperature, etc. I don't know what other...

That's exactly what I meant! The "constant flow rate" is only indicative (by product manufacturer). The actual flow rate seems decreasing as baloon deflating (from experimental data). Looking forward to your solution!

A drug delivery infusion pump is made out of thick synthetic rubber and has a very small outlet. The balloon pump is filled with 500mL liquid drug and is now inflated into a ball shape. The drug will exit from the very small outlet at a nearly (but not always) constant flow rate of 5mL/hr (takes...
