1/1

Find Air flow of Fan when know Power & Diff pressure

N = [(Q x Pt)/eff.] x [gas density (kg/m3) + dust in gas (kg/m3)] x [9.81/1000]

Pt 270 Diff Total pressure; Pt = Ps + Pd (mmWg)

N 650 Fan power consumption (kW)

Q ?? Flow rate at inlet (m3/s)eff 0.9 Fan efficiency (normally 0.85-0.9)

Gas densit 1.0 (kg/m3) ==> need to check Ps and Temp

Dust conte 1.0 (kg/m3)

Q (m3/s) 110 m3/s

397,554 m3/h
