DIY_EFI Digest V4 #694 Airflow measurement

[Carl Summers]

Hi Chris,
     I'm pretty sure it goes back to the same old thing....compressors,
blowers, swamp coolers were all measured in cubic feet transferred and not
by mass transferred.....pretty tough for the entrepeneurs way back to
explain it any different than this machine can blow 600 cubic feet of air
per minute....it still takes a computer to figure the airflow and air
temperature and make a calculation of (supposed)actual grams per second or
lbs per minute....hth's

Hello,

Can someone tell me why cylinder heads, intakes, throttlebodys, etc. etc.
airflow numbers are quoted in CFM? Would it be better if they were given in
lbs/min? Why or why not? I understand why compressors are rated this way
just not why other engine componets are not.

Thanks             Chris Skarzenski       pcs74 at swbell.net
