WebThe performance of low-pressure axial flow fans is directly affected by the three-dimensional bending and twisting of the blades. A new blade design method is adopted in this work, where the radial distribution of blade angle and blade bending angle is composed of standard-form rational quadratic Bézier curves. Dendrite Net is then trained to … WebThe second fan law states that the change in pressure is proportional to the square of the change in speed: where: P = pressure (in. w.g.) ρ = air density (lb/cu.ft) The change in the power requirement is proportional to the cube of the change in speed, as shown in the equa-tion of the third fan law: where: Hp = fan power requirement (hp) Q N ...
