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



Study air heating
