INTRODUCTORY FLUID MECHANICS KATZ
COMPLETE COURSE REVIEW GUIDE
◉ What are the two major areas of Fluid Mechanics?
Answer: Fluid statics (fluids at rest) and fluid dynamics (fluids in
motion).
◉ What is hydrodynamics?
Answer: The flow of liquids or low-velocity gas flows where the gas
can be considered incompressible.
◉ Define a fluid.
Answer: Any liquid or gas that cannot sustain a tangential or
shearing force when at rest and undergoes continuous change in
shape under stress.
◉ What are the two categories of fluids?
Answer: Ideal fluids and real fluids.
◉ What are the characteristics of ideal fluids?
Answer: Assumed to have no viscosity, incompressible, uniform
velocity, no friction between layers, and no turbulence.
, ◉ What are the characteristics of real fluids?
Answer: Exhibit viscosity, non-uniform velocity, compressible, and
experience friction and turbulence.
◉ What is laminar flow?
Answer: A type of flow where the velocity at any fixed point in the
fluid is constant, resulting in smooth flow in parallel layers.
◉ What is turbulent flow?
Answer: A type of flow where the velocity at any fixed point in the
fluid can vary, resulting in disrupted layers of flow.
◉ What is viscosity?
Answer: A measure of a fluid's resistance to flow.
◉ What is a Newtonian fluid?
Answer: A fluid whose viscosity remains constant regardless of the
shear applied.
◉ Give examples of Newtonian fluids.
Answer: Water, mineral oil, gasoline, and alcohol.
