A small sphere of radius \(r\) is dropped in a viscous liquid. When it is moving with terminal velocity in the liquid, the relation between the rate of heat produced \[ \left(\frac{dQ}{dt}\right) \] and \(r\) is
In a tube, a liquid is flowing as shown in the diagram. The correct order of the velocity (u) of liquid flowing in this tube is: figure [H]

Two drops of same radius are falling through air with steady velocity of $5~cms^{-1}$. If the two drops coalesce, the terminal velocity would be:
The terminal velocity v of a small spherical ball of radius r falling through a viscous liquid is directly proportional to:
Terminal velocity of a small sphere falling in viscous liquid varies with radius as:
A liquid rises to a height of $4 \text{ cm}$ in a capillary tube of radius $r$. If another capillary tube of radius $r/2$ is dipped in the same liquid, the height of liquid rise will be}
The rate of flow of a liquid through a capillary tube of radius $r$ and length $l$ under a pressure difference $P$ is proportional to
A cylindrical metal box whose flat surface has an area of \(0.01\text{ m}^2\) rests on liquid of \(0.3\text{ mm}\) thickness. If upon applying a horizontal force of magnitude \(\frac{1}{3}\text{ N}\), the box slides with a constant speed of \(0.09\text{ m s}^{-1}\), the coefficient of viscosity of the liquid is nearly
