The value of constant proportionality is found to be $$\frac {\pi }{8}$$ from experiment. So, the net force acting on the body is zero and the ball starts to fall with a constant velocity, i.e. the rate of change of pressure with length), Coefficient of the viscosity of liquid, η. 6 meters. directly proportional to the fourth power of the radius of a tube.

Last updated 20 January 2015.  Lecture 7  Let (Ρ) be the density of the material of the ball.

an integration can be made to get an expression for the velocity. \: V \propto \eta ^c \dots (iii) , \begin{align*} V &\propto \left (\frac {P}{ l}\right )^a r^b \eta ^c \\ V &= K\left (\frac {P}{ l}\right )^a r^b \eta ^c \dots (iv) \\ \end{align*}, Writing dimensional formula on both sides we have,[M^0 L^3 T^{-3}] = \left [ \frac {ML^{-1}T^{-2}}{L} \right ]^a . Where k = π/8, a constant of proportionality. common interests and common objectives are not necessary for society. This can also be clearly understood. This is the expression for the coefficient of viscosity of liquid or fluid. You can find us in almost every social media platforms. Adjustments to blood flow are primarily made by varying the size of the vessels, since the …
