converting Litres per second to CFM

Hi

Most aircompressors quote CFM flow rates, new compressors out are in litres per second. How do I convert Litres per second to CFM?

Thanks
Ryan

You can do that conversion here:

CFM is the symbol for cubic foot/minute

1 cubic foot/minute = 0.471 947 45 liter/second

Re: converting Litres per second to CFM

I'm trying to convert 117 CFM to Liters per square meter per second....

having trouble and could use some help.

thanks

you can't convert cubic measurements (cubic feet per minute) to square measurements (liters per square meter per second) directly

however 117 cubic feet per minute is equal to 55.217 851 65 liters per second

Two problems:
*The math is inverted
*The flow is rated in raw, atmospheric air. The 45 L tank is at pressure, 5 kgf/cm² (I assume that's what he meant) is 4.8 atm, so the 45 L is the equivalent of 216 L at 1 atm.
(I have no idea what the temperature of the compressed air will be, depending on cooler performance, so I'll just ignore it). 216 L/ 113L/min = 1.9 minutes.

(Ideally both temperature and pressure should be known and used to calculate how many standard cubic feet or liters are required to fill the 45 L tank. Some heating of the compressed air is unavoidable, so the tank contents will be somewhat less than 216 standard liters)

Recognize that 1 L = 1 dm³

5 dm³/h x 1h/60 min x (1ft/3.048 dm)³ = 0.00294 ft³/min
