Calculation of parallel connection of fans
Full pressure: Pt double = Pt single
Static pressure: Pst double = Pt single
Dynamic pressure: Pd double = Pd single
Flow rate: Q double = Q single X 2
Noise: LwiA double = LwiA single + 3dB
*RPM: n double = n single X 1.05 *Shaft power: N double = N single X 2.15
* Indicates that it is not possible to verify for the time being
