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.
