lbs/min conversion
lbs/min conversion
(OP)
I would like to convert x-lbs/min of air flow into x-CFM. This seems to be a simple exercise but I'm stumped. The air flow is to be measured within a 2.875 ID tunnel and I would like to use an anemometer. Got any ideas? I'll be honest here. I'm a bit ignorant on this subject.

If you want standard conditions, the density you use has standard pressure and standard temperature. If you want actual conditions use suction pressure and suction temperature for you density calculation.

"Belief" is the acceptance of an hypotheses in the absence of data.
"Prejudice" is having an opinion not supported by the preponderance of the data.
"Knowledge" is only found through the accumulation and analysis of data.

Density is mass over volume. No need to worry of time because we are saying per minute in both situations. So you need density of the flow under the said conditions.

mass flow rate=volume flow rate * density
You'll also need to have some idea of the pressure and temperature to produce a halfway accurate answer, in addition to the air velocity. Some additional information about the uniformity of flow would also be needed or assumed.
