WHAT ARE FANS?

FANS ARE DEVICES WHICH PRODUCE PRESSURE BY ALTERING THE AIRFLOW VELOCITY IN AN AREA. A FAN PRODUCES THIS PRESSURE BECAUSE THE ROTATING BLADES IMPART VELOCITY TO THE AIR BY CHANGING ITS KINETIC ENERGY.

VARIOUS FAN LAWS GOVERN HOW THE VELOCITY IS CHANGED BY THE FAN.

THE NEXT SECTION EXPLAINS IN A NUTSHELL HOW THE FAN OPERATES ACCORDING TO THESE LAWS.
