Question

12. What is the average fluid velocity in a 2.00mm diameter artery, if a 0.500T field across it creates a 5.0mV Hall voltage?

science physics

Answer 1

Answer #1

Solution :

Here we have :

Diameter of artery : d = 2 mm = 2 x 10^-3 m

Magnetic field : B = 0.5 T

And, Hall Voltage : V_hall = 5 mV = 5 x 10^-3 V

.

Since, Hall Voltage is given by : V_hall = v B d

Where, v is the average velocity of the fluid.

∴ (5 x 10^-3 V) = v (0.5 T)(2 x 10^-3 m)

∴ v = 5 m/s
