Does anyone know of a good head loss chart for water to air heat exchangers?

Thanks for the info. The heat exchanger is fairly large (24 by 24). however I only need about 100k BTU out of it. I ordered a taco 0015 3 speed circulator, and panicked because I have very little piping (8 feet of 1.25 copper to and from the heat exchanger to the boiler), but didn't consider the headloss through the heat exchanger. it looks like the 0015 will handle it ok

thanks!
