Default Re: What about volumetric loss in blowers and fans at high altitudes

Thanks for your response!

I have one more question:

- If I have less air than at standard conditions for my blower, when I measure with a flowmeter I could get the air flow (VOLUME) , so I could get the SAME VOLUME that at standard conditions (with a minor density) or I`ll have less volume (and less density?)

Taking in count your recomendations I made a volumetric convertion for my blower:

- About blower:
Air Flow: 492 m3/min
Power: 355 KW
Intake pressure: 101 KPa
Pressure Rising 29.34 KPa

- About environmental Conditions:
Altitude: 3850 m.a.s.l.
Pressure: 0.64 bar
Temperature: 11ºC
Relative Humity: 37%

- About "Standard Conditions:
Pressure: 1 bar (101 KPa)
Temperature: 20ºC
Relative Humity: 36%

*Taking in count every thing above, I'll have 311 m3/min...

But I'll like to know if really I could reach this 311 m3/min or less, and how it's for a combustion process I'll like to know about MASS variation.

I don't have a manometer for this blower yet.

Now, I have the following parameters in operation:
162 m3/min , having 56% opening (at derivation valve after blower)


My doubt is just because of AMBIENT PRESSURE, air density is affected ??? or What else???
