Mechanical Properties of Fluids

Pressure due to a fluid column; Pascal’s law and its applications (hydraulic lift and hydraulic
brakes), effect of gravity on fluid pressure.
Viscosity, Stokes’ law, terminal velocity, streamline and turbulent flow, critical velocity,
Bernoulli’s theorem and its applications.
Surface energy and surface tension, angle of contact, excess of pressure across a curved
surface, application of surface tension ideas to drops, bubbles and capillary rise.

Bernoulli’s Theorem

Bernoulli’s Theorem

If an ideal liquid is flowing in streamlined flow then total energy, i.e., sum of pressure energy, kinetic energy and potential energy per unit...
Variation of Pressure with Depth

Variation of Pressure with Depth

Consider a fluid at rest in a container. In Fig.1 point 1 is at height h above a point 2.The pressures at points 1...
