Lecture 1 - Introduction to Fluids, Why Study Fluid Mechanics, and What are Fluids? In this very first segment, we introduce fluids, motivate their study, and go over the definition of fluids.

Lecture 2 - Important Fluid Properties: In this segment, we discuss important fluid properties, including density, specific weight, specific gravity, pressure.

Lecture 3 - Viscosity Concept - Derivation and Discussion: In this segment, we derive the viscosity expression for a Newtonian fluid. We also introduce kinematic viscosity, as well as discuss various Non-Newtonian fluids.

Lecture 4 - Viscosity Example - Terminal Velocity on an Inclined Plate: In this segment, we go over step by step to obtain terminal velocity for a block sliding down an inclined surface. We find the forces on the block given the viscosity of the glycerin between the block and the inclined surface.

Lecture 5 - Viscosity Example - Multiple Fluid Interactions: In this segment, we go over step by step instructions to obtain a force or shear stress for cases involving multiple fluids interaction. We demonstrate how to obtain a particular velocity of a plate, given viscosity and geometrical dimensions.

Lecture 6 - Viscosity Example - Non-Uniform Velocity Profile: In this segment, we demonstrate how to obtain forces and shear stresses from non-uniform velocity distribution, given a viscosity.

Lecture 7 - Compressibility of Fluids: In this segment, we discuss and quantify the compressibility of fluids, introduce bulk modulus.

Lecture 8 - Surface Tension: In this segment, we go over surface tension and highlight a few applications where the surface tension is the dominant mechanism for fluid flow phenomena.
