# What is an example of a fluid flow practice problem?

Oct 1, 2015

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 $3 c {m}^{3} / \min$ through a $50 m m$ long needle with internal diameter of $0 , 55 m m$?
Assume the pressure of the blood in the vein is $15 m m H g$.
The density of the blood is $1 , 05 g / c {m}^{3}$ and its viscosity is $1 , 5 \times {10}^{- 3} P a . s$
