Question

Use Poiseuille's Law to calculate the rate of flow in a small human artery where we can take η = 0.028, R = 0.008 cm, l = 2 cm, and P = 5000 dynes/cm2. (Round your answer to three significant figures.)

Answer 1

1.435 x 10^-4 cm^3/s

Step-by-step explanation:

coefficient of viscosity, η = 0.028 poise

Radius, R = 0.008 cm

length, l = 2 cm

Pressure, P = 5000 dyne/cm^2

The Poiseuille's formula is given below

`V=(\pi PR^(4))/(8\eta l)`

Where, V is the rate of flow, that means volume flowing per second

`V=\frac{3.14*5000 * {0.008}^(4)}{8 * 0.028 * 2}`

V = 1.435 x 10^-4 cm^3/s

Thus, the rate of flow is 1.435 x 10^-4 cm^3/s.
