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
[tex]V=\frac{\pi PR^{4}}{8\eta l}[/tex]
Where, V is the rate of flow, that means volume flowing per second
[tex]V=\frac{3.14\times5000 \times {0.008}^{4}}{8 \times 0.028 \times 2}[/tex]
V = 1.435 x 10^-4 cm^3/s
Thus, the rate of flow is 1.435 x 10^-4 cm^3/s.
