This chart compares the heat rejection rate (cooling capacity) of three different types of radiators tested on an old Ford Street Rod. Coolant flow rate is held constant at 7 gpm (typical flow at idle perhaps, not sure where its being measured ???). It graphs the heat rejection for each radiator versus air flow through the radiator core. It is comparing 3 diff rad designs/materials at different CFMs through the core. The more air flow you have for a given coolant flow rate (7 gpm in this example) , the higher the heat rejection, basically linear in this example. The author of this graph is most likely selling the high efficiency radiator showing the improvement over the other two designs. To sum it up, the radiator at the top of the chart appears to be the most efficient at a low coolant flow rate (7 gal/min) over all air flows tested. Ya see how important rad core/tank design is? I learned something here.
