Fan Performance Curves
This point can then be plotted on a chart that has static pressure on the vertical
axis and airflow on the horizontal axis.
Additional data from the fan tests establish other static pressure and
corresponding airflow performance points for a given rotational speed
(revolutions per minute or rpm).
