And does it matter if you are going from 200F to 100F or 500F to 400F? ie, is it temperature dependent?Thanks
How many BTU/hr needed to cool 500 CFM of air 100F degrees?

It takes approximately 1.08 BTU/hr to cool a CFM by 1 degree, so I'll let you calculate that. 
For the second part, no, it isn't quite constat over large temperature differences. At 500F, it is only about 5% larger. You can google for tables and/or equations for specific heat at various temperatures.
