Question
![**Question 3**
Given tubes of equal length and diameter (and the inflow / outflow pressures below), which will have the fastest flow of blood? **You may choose more than one answer.**
- [ ] in = 120 mm Hg, out = 60 mm Hg
- [ ] in = 100 mm Hg, out = 65 mm Hg
- [ ] in = 225 mm Hg, out = 175 mm Hg
- [ ] in = 75 mm Hg, out = 20 mm Hg
- [ ] in = 70 mm Hg, out = 10 mm Hg
- [ ] in = 120 mm Hg, out = 180 mm Hg
**Explanation:**
In this question, the rate of blood flow is determined by the pressure difference (ΔP) between the inflow and outflow. A higher pressure difference results in a faster flow. The objective is to identify the tube or tubes with the greatest pressure differential, thus enabling the fastest flow of blood.
The pressure differences are calculated as follows:
1. 120 mm Hg - 60 mm Hg = 60 mm Hg
2. 100 mm Hg - 65 mm Hg = 35 mm Hg
3. 225 mm Hg - 175 mm Hg = 50 mm Hg
4. 75 mm Hg - 20 mm Hg = 55 mm Hg
5. 70 mm Hg - 10 mm Hg = 60 mm Hg
6. 120 mm Hg - 180 mm Hg = -60 mm Hg (Flow will not occur in the intended direction)
From the calculations, options 1 and 5 have the highest positive pressure difference, suggesting they will have the fastest flow of blood.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2698fe29-e53d-495d-9925-17a6dc6547ed%2Fb4d31e00-8e6e-4c2c-8faa-591396b36161%2Fmhdy1wp_processed.jpeg&w=3840&q=75)
