Substances that can flow is called fluid. Thus both liquids and gases are fluids.

Pressure applied to an enclosed fluid is transmitted undiminished to every portion of the fluid and the walls of the containing vessel. This law was first formulated by
Two liquids of densities $d_1$ and $d_2$ are flowing in identical capillary tubes uder the same pressure difference. Ift $t_1$ and $t_2$ are time taken for the flow of equal quantities (mass) of liquids, then the ratio of coefficient of viscosity of liquids must be
Anvils made of single crystals of diamond, with the shape as shown in Figure, are used to investigate behaviour of materials under very high pressures. Flat faces at the narrow end of the anvil have a diameter of $0.50\; mm$, and the wide ends are subjected to a compressional force of $50,000 \;N$. What is the pressure at the tip of the anvil?
Water is filled in a tank upto $3 \,m$ height. The base of the tank is at height $1 \,m$ above the ground. What should be the height of a hole made in it, so that water can be sprayed upto maximum horizontal distance on ground?
Water flows out of the hole on the side of a bucket and follows a parabolic path. If the bucket falls freely under gravity, ignoring air resistance, the water flow
A body is just floating on the surface of a liquid. The density of the body is same as that of the liquid. The body is slightly pushed down. What will happen to the body
An ornament weighs $10\, g$ in air and $6\, g$ in water. Density of material of ornament is $20\,\frac{g}{{cc}}$. The volume of cavity in ornament is ........ $cc$
The bulk modulus of a liquid is $3 \times 10^{10}\, Nm ^{-2}$. The pressure required to reduce the volume of liquid by $2 \%$ is ........ $\times 10^{8}\; Nm ^{-2}$
