This document contains a syllabus and introduction for a fluid mechanics course. It outlines topics that will be covered, including physical properties of fluids, fluid statics, pressure, buoyancy, and measurement of pressure. Fluid mechanics deals with fluids at rest and in motion, and their interaction with solids. It is divided into subcategories like hydrodynamics, hydraulics, gas dynamics, and aerodynamics. A key distinction between solids and fluids is that fluids continuously deform under stress, whereas solids can resist deformation.

2. SYLLABUS
• Introduction: Fluids and continuum, Physical
properties of fluids, density, specific weight, vapour
pressure, Newton’s law of viscosity.
• Ideal and real fluids, Newtonian and non-Newtonian
fluids.
• Fluid Statics- Pressure-density-height relationship,
manometers, pressure on plane and curved surfaces,
center of pressure, buoyancy, stability of immersed
and floating bodies, fluid masses subjected to
uniform accelerations, measurement of pressure.

3. INTRODUCTION
• Fluid mechanics is defined as the science that deals with the
behavior of fluids at rest (fluid statics) or in motion (fluid
dynamics), and the interaction of fluids with solids or other fluids
at the boundaries.
• Fluid mechanics is also referred to as fluid dynamics by
considering fluids at rest as a special case of motion with zero
velocity
• Fluid mechanics itself is also divided into several categories.
• The study of the motion of fluids that can be approximated as
incompressible (such as liquids, especially water, and gases at low
speeds) is usually referred to as hydrodynamics.
• A subcategory of hydrodynamics is hydraulics, which deals with
liquid flows in pipes and open channels

4. • Gas dynamics deals with the flow of fluids that undergo significant
density changes, such as the flow of gases through nozzles at high
speeds.
• The category aerodynamics deals with the flow of gases (especially
air) over bodies such as aircraft, rockets, and automobiles at high or
low speeds
• A substance in the liquid or gas phase is referred to as a
fluid
• Distinction between a solid and a fluid is made on the basis
of the substance’s ability to resist an applied shear (or
tangential) stress that tends to change its shape.
• A solid can resist an applied shear stress by deforming,
whereas a fluid deforms continuously under the influence
of a shear stress, no matter how small.
• In solids, stress is proportional to strain, but in fluids,
stress is proportional to strain rate
