Where: Q - flow (m3 / h)
P - total pressure (PA)
D2 - diameter of outer edge of impeller blade (m)
U2 - linear speed of outer edge of impeller blade (M / s)
ρ 1 - intake air density (kg / m3)
K ρ - compressibility coefficient of total pressure
NIN - internal power (kw)
NRE - required power (kw)
η m - mechanical efficiency
(1 for type a drive, 0.98 for type D drive)
K - motor reserve coefficient
When the use state is non-standard state, the performance of non-standard state must be converted to the performance of standard state, and then the blower shall be selected according to the conversion performance. The conversion formula is as follows:
Q0=Q×n0/n(m3/h)
P0=P×(n0/n)2×ρ0/ρ×Kp/ Kp0(Pa)
Nin0= Nin×(n0/n)3×(ρ0/ρ)    (KW)
ETA in0= eta in
η in internal efficiency
N - speed (R / min)
