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.

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.

An example of a fluid flow practice problem could involve calculating the velocity profile of fluid flow through a pipe, determining the pressure drop across a venturi meter, or analyzing the flow rate of water through an irrigation system.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
