Question

What is an example of a fluid flow practice problem?

Answer 1

Here is a nice practice problem I have given for you below - it is an application to every day life of blood flowing through a needle into a patient's vein in a hospital.
Try the problem, post your answer, and I will mark it for you once you completed it.

Explanation:

How high above the point of a needle must a container of blood plasma be placed to ensure the plasma enters a patient's vein at `3cm^3//min` through a `50 mm` long needle with internal diameter of `0,55mm`?
Assume the pressure of the blood in the vein is `15mmHg`.
The density of the blood is `1,05g//cm^3` and its viscosity is `1,5xx10^(-3)Pa.s`
You may use laminar flow.
