That's what I was afraid of. Any recommendations on readings as to why it can't be done?

Thank you for this explanation! Since I am curious about calculating absolute pressure from non pressure measurements I am still going to pursue the answer to my question. Do you have any equations or concepts about pressure I should read up about that might be useful in realizing an equation...

Does whether I consider it or not matter in the above pressure equation? Sorry, it's been a few years since I've studied any physics. I began looking at how I can get absolute pressure of blood (colloquially blood pressure) from blood velocity measurements. I then realized that how I was going...

No, I don't want to assume energy loss due to drag. -GM

Sorry I did not say this explicitly but there is a Δv in the above equation! I would hope velocity would not be constant otherwise pressure would be zero in the above formula. Looking into this myself, I'm thinking I might be hitting on something like the pressure that does work on a volume...

The inspiration for the above work is the circulatory system. So the source of the acceleration would be the heart. Since this is just a theoretical problem, the boundary conditions on pressure can be whatever, but I suppose the heart can be approximated as a diaphragm pump. -GM

Hello all, I am posting this question here in this thread and not the homework thread since it is not a homework problem but something I have been working on myself. Let us imagine a fluid flowing through a pipe, we can measure pipe diameter and fluid velocity. The density of the fluid is also...
