Mechanical Properties of Fluids

Both liquids and gases can flow hence they are called $\_\_\_\_$.

If the lower end of a capillary tube touches a liquid whose angle of contact is ${90}^{\circ}$, then the liquid

In most liquids, with rise in temperature surface tension of liquid

Construction of submarines is based on

The liquid (mercury) meniscus in capillary tube will be convex if the angle of contact is

The viscous force between two liquid layers is

In most liquids, with rise in temperature, surface tension of a liquid

A capillary tube stands with its lower end dipped into liquid for which the angle of contact is 90°. The liquid will

Potential energy of a molecule on the surface of a liquid as compared to another molecule inside the liquid is

When two capillary tubes of different diameters are dipped vertically in a liquid, the rise of the liquid in the capillary tube

The wettability of a surface by a liquid depends primarily on

Water rises up to a height h in a capillary tube of certain diameter. This capillary tube is replaced by a similar tube of half the diameter. Now the water will rise to the height of

In case of a liquid which does not wet a solid surface, the force of adhesion

Surface tension of a liquid is numerically equal to

In case of liquid, if Reynold's number ' $R_{n}$ ' is 1450 , then the flow of liquid will
