Fluid Mechanics Examples of fluids Glycerine blood Water Types of fluid Newtonian fluids It has constant viscosity, with zero shear rate at zero shear stress. Non-Newtonian It does not follow Newton's law of viscosity, i.e., constant viscosity independent of stress Ideal plastic Fluid A fluid having the value of shear stress more than the yield value Real fluids fluids which have viscosity, surface tension, shearing force, and compressibility Incompressible The fluid with constant density Compressible the fluids with variable density Applications Bernoulli’s
Principle Attraction between two parallel moving boats Archimedes principle Fish floating floating of a big ship Pascal’s Law Hydraulic brakes hydraulic lift Properties Specific Volume units are m^3/kg the ratio of the substance volume to mass Pressure the force applied perpendicular to the surface of an object per unit area over which that force is distributed Temperature Units are kelvin and celsius It is average kinetic energy of particles in an object Specific weight Units are N/m^3 and lb/ft^3 It is weight per unit Volume of a material Density Units are g/cm^3 It is defines as mass per unit.
