Funny Q:? in that:
Are you talking Forced air, boiler, what do you want your delta T to be?, Application etc... A/C sometimes ratted at 400cfm/ton, but not always due to conditions that have to be met. I have seen cooling specs. for 325cfm/ton. If your Q? for cfm also must have the size of duct, it's current profected static pressure etc..
I guess I would like to know what you are trying to do???

Depends upon efficiency
80% is abour 130 cfm per 10,000 btu
90% is about 150 cfm per 10,00 btu
This is for heating airflow0
