Speaker: Dr. Matt Anderson-Talking about fluid properties

·         Show examples with fluids

·         Fluid Mechanics

o   What’s a fluid

§  Fluid vs. Solid (solid-rigid structure)

§  Spacing of molecules-large for fluid, small for solid

§  Shearing stress applied-fluid deforms continuously under any amount of shear

§  Solid initially deforms

§  Fluid goes into flow, proportional to strain rate

§  Solid proportional to strain

o   Properties

§  Viscosity-fluids resistance to shear

§  Non-Newtonian fluids ex. Blood, paint (no drips, not much flow), toothpaste

·         Mixture: no shear not resistant to flow, shear-becomes solid (chunky). Corn starch and water

§  Density

§  Buoyancy-force that opposes gravity

·         Resultant force due to a displaced fluid

·         Proportional to density of the fluid-Archimedes diver

§  Surface Tension-forgotten about fluid property

·         Attractive force at fluid-fluid interface (usually gas-liquid)

·         Quantified: force/distance

·         Introduce a solid-get wetting or non-wetting surface-capillary action

o   Fluid Dynamics

§  Fluid is not static

§  Velocity field- velocity vector

§  Fluid has energy associated with its motion (kinetic energy)

§  Inertia

§  Bernoulli’s Equation-flow steady

·         Energy conservation along a streamline

·         Have to conserve mass

§  Pressure: force/area [psi]

·         Absolute pressure=atmospheric pressure + gauge pressure

·         Gauge pressure

§  Unbalanced forces

·         Newton’s Second Law-ex. Ping Pong Ball shooting through the tube
