The answer depends on many things....

A btu is a british thermal unit, which is the measure of energy to raise one CC of water one degree Celcius.

But you probably want to know about airflow in cfm (not water), and the amount of cooling (or heating) available in 1 cfm or airflow.

In Houston, we tend to cool things more than heat. We also try to drive moisture out of the air (dehumidify), but I won't discuss that now. The general equation to answer your question is like this: Qsens = cfm * 1.08 * (Tin - Tout) <-- "delta T"

You need to determine what your "delta T" is. For cooling a space to 75degF, your dT is usually 20degF with your supply air temperature (SA=55) and your return air temperature (RA=75). This has been idealized and simplified. For cooling, 1cfm will do about 21.6btu/h of cooling. For heating, (SA=90, RA=68, 1cfm => 23.76btu/h)
