What is the speed of the blood?

In summary, the conversation discusses the calculation of the speed of blood flowing through an artery, given its inside diameter and the magnetic field it passes through. The formula v= E/B is mentioned, but since the charge is not given, the approach is unclear. However, it is suggested that the electric field can be found by knowing the potential difference and the geometry of the blood vessel. With this information, the problem becomes solvable.

The artery in Figure 22-11 has an inside diameter of 2.30 mm and passes through a region where the magnetic field is 0.065 T.


(a) If the voltage difference between the electrodes is 175 µV, what is the speed of the blood?
m/s

quite honestly, i do not know how to go about this one maybe v= E/B BUT E is not given and i don,t know of an equation to acquire E from the above eaqn, since no charge is given. how should i go about. thks

you can find E because you know the potential difference and the geometry of the blood vessel. The magnitude of the electric field depends on the distance a point is from a potential difference.

thank very solvable now :)
 

1. What is the speed of blood in the human body?

The speed of blood flow in the human body varies depending on the location. In the arteries, blood can travel at speeds of 1-3 feet per second, while in the capillaries, it slows down to 0.00008 feet per second. In the veins, blood moves at a speed of 0.08 feet per second.

2. How is the speed of blood flow measured?

The speed of blood flow is typically measured in centimeters per second (cm/s) or feet per second (ft/s). This can be done using various imaging techniques such as Doppler ultrasound or magnetic resonance imaging (MRI).

3. What factors affect the speed of blood in the body?

The speed of blood in the body can be affected by several factors including the diameter of the blood vessels, the viscosity of blood, and the pumping action of the heart. Other factors such as exercise, body position, and health conditions can also influence blood flow speed.

4. What is the average speed of blood flow in the body?

The average speed of blood flow in the human body is approximately 3 miles per hour (mph) or 4.8 kilometers per hour (km/h). However, this can vary depending on individual factors and the location of blood flow within the body.

5. Why is it important to know the speed of blood flow?

The speed of blood flow is an important factor in maintaining overall health. Changes in blood flow speed can indicate underlying health issues such as blockages or narrowing of blood vessels. It is also important in delivering oxygen and nutrients to tissues and removing waste products from the body.
