    So that actually is a relative minimum value. Now we get over here to d. And really, by the same argument that we used for b, that is also at d our function takes on another relative maximum point. And then e, when x is equal to e, this is the function hitting what could really be considered a classic relative minimum point.

  • Axial fan design Wikipedia

    Factors which determine the performance of the fan include the number and shape of the blades. Fans have many applications including in wind tunnels and cooling towers. Design parameters include power, flow rate, pressure rise and efficiency. Axial fans generally comprise fewer blades (two to six) than ducted fans. Axial fans commonly have larger radius and lower speed (ω) than ducted fans .
