heat loads.

Found this to be a good thread. I'm stuck with calculating heat load, with answer expressed in CFM. What would be the formula if I had 5,000 gal/hr of cooling water with a 10 degree delta T?

mass flow * specific heat * delta temperature

TTFN

IRstuff's answer will give you BTU/hr. For water in HVAC applications, a simplification is

500*GPM*(delta-T)

To convert to air flow in CFM, you'll need to know the difference in supply air temperature and space temperature, plus the load. Not enough info given.

Best to you,
