2. Basics of Fluid Mechanics- 1 (Contnd.)
Fluid mechanics encompasses various properties and phenomena associated with fluids, including their behaviors under different conditions. Key concepts such as viscosity, bulk modulus of elasticity, and surface tension are explored alongside their mathematical descriptions and applications. The chapter also discusses gas laws, particularly isothermal and isentropic processes, and examines calculations related to pressures and temperatures within compressed fluids.

What we have learnt
- Viscosity affects the flow characteristics of fluids.
- Bulk modulus of elasticity relates volume change to pressure change.
- Surface tension is critical in understanding the behavior of droplets and bubbles.
Key Concepts
- -- Viscosity
- A measure of a fluid's resistance to flow and deformation.
- -- Bulk Modulus of Elasticity
- A measure of a substance's resistance to uniform compression.
- -- Surface Tension
- The tension of the surface film of a liquid caused by intermolecular forces.
- -- Isothermal Process
- A thermodynamic process in which the temperature remains constant.
- -- Isentropic Process
- A reversible adiabatic process where entropy remains constant.
- -- Vapor Pressure
- The pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature.
