3 Integral analysis

Analyze existing flows, and quantify the forces and moments associated with them
The Reynolds Transport Theorem; Mass conservation; Change of linear momentum; Change of angular momentum; Energy conservation; the Bernoulli equation; Limits of integral analysis.

4 Derivative analysis

Predict fluid flow in the most general terms possible, and understand the nature of CFD

5 Pipe flow

Understand duct flow, and quantify pressure losses in pipe installations
Inviscid flow in ducts; Viscous laminar flow in ducts; Viscous laminar flow in cylindrical pipes; Viscous turbulent flow in cylindrical pipes.

6 Scale effects

Scale flows and measurements up and down to facilitate observation
