Blower Differential Pressure
Blower Differential Pressure
(OP)
I am new to blowers and need a little help. If I have a inlet pressure of 12 psia on the inlet side of the blower and a differential pressure of 6 psi what does that tell me? I expect it means the outlet pressure is 6 psi and 6 psi is lost to the equipment? If I was using this blower for aeration would the available psi for a diffuser be the 6 psi minus the friction losses? Thanks for the help





RE: Blower Differential Pressure
Outlet pressure minus friction losses is correct for diffusers.(Then consider depth of water)

RE: Blower Differential Pressure
psig is pressure relative to a reference point, typically ambient pressure (usually safe to assume 14.7 psia, unless your calculation is for a pressure relative to that in a liquid column, e.g. at seabed conditions).
12 psia would equal -2.7 psig.
Ask your supplier what the blower discharge pressure is.
RE: Blower Differential Pressure
A differential pressure of 6 psi across the blower should be a discharge pressure gauge reading of 6 psig.
