143388 A copper ball of radius $3.0 \mathrm{~mm}$ falls in an oil tank of viscosity $1 \mathrm{~kg} / \mathrm{m}$-s. Then, the terminal velocity of the copper ball will be (Density of oil $=1.5 \times 10^{3} \mathrm{~kg} / \mathrm{m}^{3}$, Density of copper $=9 \times 10^{3}$ $\mathrm{kg} / \mathrm{m}^{3}$ and $\mathrm{g}=10 \mathrm{~m} / \mathrm{s}^{2}$.)

143390 The Reynold's number for a liquid flow in a tube does NOT depend on

143392 A metallic spherical ball of mass $M$ is dropped into a liquid and after some time it reaches a terminal velocity of $v$. If another spherical ball of mass $8 \mathrm{M}$ made of the same metal is dropped into the same liquid, then its terminal velocity will be (assume the spheres to be uniformly dense)

143393 The flow rate of water from a tap of diameter $1.25 \mathrm{~cm}$ is $\mathbf{3}$ litres per minute. If coefficient of viscosity of water is $10^{-3}$ Pa.s, the nature of flow is

143389 Assertion: For Reynold's number $R_{e}>2000$, the flow of fluid is turbulent.
Reason: Inertial forces are dominant compared to the viscous forces at such high Reynold's numbers.
