4 cards from this section. Quick, good the night before a test.
What happens to fluid velocity at a stationary surface?
Think about the interactions between fluid layers and the surface.
Define viscosity in your own words.
Consider how sticky or runny a liquid is.
What is shear stress a measure of?
Focus on the interaction between fluid layers and surfaces.
True or False: All fluids are Newtonian.
Think of examples like ketchup and honey.
Determine how the force required to move a plate through a fluid changes as the fluid's temperature is increased from 20°C to 80°C, if the initial viscosity is known.
Review how temperature influences viscosity and apply it to the calculations.
In a laboratory, a non-Newtonian fluid shows an increasing viscosity with increased shear rate. Describe how this behavior could impact industrial applications.
Think about how a dilatant fluid behaves under stress.
