Study and measure velocity
Different measurement systems: Pitot tube, anemometer, diaphragm
Study equations of flow rate vs pressure drop
Determine the velocity profile relative to the axis of a pipe
Study and measure pressure drops
At a singularity: butterfly valve
Due to friction: straight pipe
Study a fan
Fan characteristics
Useful power as a function of flow rate and maximum yield
