Unit 34: Pulsatile Flow
Practice Problems
Note: problem difficulty is ranked using a star system.
(*) One-star problems are fundamental to the unit, and can be done relatively quickly. Use these problems to introduce yourself to the material.
(**) Two-star problems are more difficult, and require an understanding of one or two key concepts. Use these problems to test your understanding of the material.
(***) Three-star problems are the most difficult, and require some creative thinking in addition to a deep familiarity with multiple key concepts. Use these problems to challenge yourself; if you can complete one of these, you’re on your way to mastering the material.
**Q34.1) Consider the graph shown below which depicts the flow rate through a major blood vessel for one entire cycle of the heart. If the heart beats at 2 Hz, what volume of blood flows through the vessel in 10 minutes?
***Q34.2) Consider the graph shown below which depicts the flow speed through a major blood vessel for one entire cycle of the heart. The heart beats at 2 Hz, the vessel is 0.5cm in radius, and 20 cm³ of blood flow through the vessel each beat. Find the maximum speed at which blood flows through the vessel.
