The Fan Affinity Laws describe how airflow, pressure, and power change with the speed of the fan:

• Law 1: Airflow is directly proportional to fan speed.
• Law 2: Pressure increases with the square of fan speed.
• Law 3: Power consumption increases with the cube of fan speed.
  These laws are essential for predicting fan performance at different speeds and help engineers adjust or scale fan operation based on changes in system requirements.
