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

Answer:

1.435 x 10^-4 cm^3/s

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

$V=\frac{\pi PR^{4}}{8\eta l}$

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

$V=\frac{3.14\times5000 \times {0.008}^{4}}{8 \times 0.028 \times 2}$

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

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