Diagram is based on standard air ρ=1.2 kg/m³.Pd is system curve for
dynamical pressure part related to Fan Outlet Area (Curve for free
blowing fan). Total Pressure (the sum of the dynamic and static
pressures) is shown in relation to the Air Volume, Dynamic pressure is
shown below system line Pd and Static Pressure is shown above that
line
