Default Calculating BTUs from hot air

Can someone help me figure out the calculations for how to get the amount of BTUs you get out of hot air at a specified flow rate? I know that it depends on a lot of different factors like moisture content of the air, but I guess I'm looking for a simplified equation that ball parks things.

For example, lets say I have a solar hot air panel. I know the fan flows 100 CFM and I know that it puts out air that is 20F above ambient. How many BTUs per hour is it going to spit out?
