Compressor Actual CFM discharge

04/22/2009 11:26 AM

I have one compressor having a capacity of 750 scfm at 75% efficiency, ambient temperature is 50 Degree centigrade, what will be my compressor's discharge rate if the discharge pipe size is 2" NB or how many percent of my compressor's cfm capacity can be supply to my receiver?

Thanks,

Seth

With no load, the pressure in the receiver will eventually equal the compressor's maximum discharge pressure, which isn't stated, and neither is the length of the 2" NB pipework feeding it.

What i mean, I have one compressor having a capacity of 750 scfm; 135 psig at 75% efficiency, ambient temperature is 50 Degree centigrade, what will be my compressor's discharge rate if the discharge pipe size is 2" NB if my the total cfm required is 822 Acfm? what is the recommended air receiver tank capacity so that i can continously supply the demand cfm which will operate within 18 hours? is my compressor's capacity is enough? if it so, how many minutes my compressor should start to fill in the receiver having 124 cubic feet.

Thanks,

seth

Is there any chance of posting a system drawing?
