BENG 112B BIOMECHANICS S 2009 Homework #4 Not to be collected for a grade Review Problems: Navier-Stokes, Pipe Flow, etc. 1. Blood is flowing through a small capillary shown below. As with most capillaries, the radius of this capillary gets smaller as a function of position down the vessel as it reaches the other side of the capillary bed. The fluid in this vessel has a Reynold’s number that is small, it is incompressible, and the flow is laminar. Determine the mass flow rate (Q dot) if we treat blood as a fluid with constant viscosity μ and density ρ . 2. What is v z in a straight cylindrical pipe obeying the Navier-Stokes equation? 3. You work for a stent manufacturer who needs to know the flow rate where the stent is placed to help calculate how a drug elutes from the material. You’re told the stent is going into the left anterior descending artery, which has a roughly constant radius of 1.2mm, is 10cm in length, has a low Reynold’s number.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
