Default Grams per second-cfm?IAM of 15?

How do you convert grams per second to cfm?And is it possible to see an IAM of 15?Wasn't sure if it advanced by 2's or not.

Grams per second is mass and cfm is volume. You can't really convert them.

I've seen IAM of 15 before. Surprised me too, but apparantly it can be any integer 0-16.

Thanks!What about converting grams/second-lbs/min first and then to cfm?
Doesn't lb/m=14.47 cfm?

Probably not since the volume will change depending on pressure and temperature. If you knew the intake air temperature as well as atmospheric pressure you could get reasonably close. I got the conversions in a book at home though. Why do you need to know the CFM?

Not sure. in one cubic feet per minute there are .0691 LB/min at sea level around 70 degrees. so one lbs/min is equal to 7.5598 grams per second.

Default cubic feet -> grams per second

assuming we are talking about mass airflow
gr/s = scfm x 0.075(lbs/cu.ft.) x 453.59237(gr/lb) / 60 (sec/min)
gr/s = (scfm)*(0.075)*(453.59237)/(60)

standard [FONT='Verdana','sans-serif']temperature [/font]= 70 F
standard pressure = 29.92" Hg
standard humidity = 0%
