Hey all, I was just wondering if you could convert a SFM number into pounds per minute. The only numbers I can find for this compressor are it's CFM flow rate.

 

CFM + temp + pressure can be converted to lbs/hr.

-Max

 

Well I know aprox. how much lbs/min a 13B takes at what hp level, is there the same about guesstimate number for CFM as well max?

 

the conversion is

lbs/min/10* 144.71 = cfm

cfm/1.92 = rotary rwhp

that makes no sense.

 

How does it not make sense? I used the formula and it seemed to match a compressor map that had both lbs/min and a cfm chart.

Thanks howard.

Kooking at both of these compressor maps they seem like the S-Trim would be a pretty good choice and in it's efficency range for 350-400hp at 1 bar correct, I'm still trying to figure out compressor maps.

 

assuming you want 375 rwhp (rotary)...

375*1.92=720cfm/14.471=49.7lbs/minute.

the formula is for an Optimized engine w Optimized support systems and the 49.7 lbs/min is the absolute requirement so you'd best look for something around the 55 pound area.
