Question 149: Properties of Matter

Question

An ideal fluid flows (laminar flow) through a pipe of non-uniform diameter. The maximum and
minimum diameters of the pipes are 6.4 cm and 4.8 cm, respectively. The ratio of the minimum
and the maximum velocities of fluid in this pipe is :

Accepted Answer

Using equation of continuity
A
1
V
1
= A
2
V
2
$$ \Rightarrow $$ $${{{V_1}} \over {{V_2}}} = {{{A_2}} \over {{A_1}}}$$ = $${\left( {{{4.8} \over {6.4}}} \right)^2}$$ = $${9 \over {16}}$$

Answer

$${3 \over 4}$$

Answer

$${9 \over {16}}$$

Answer

$${{\sqrt 3 } \over 2}$$

Answer

$${{81} \over {256}}$$
