Ed, If your flap outlet area = is=20 3x20=3D60sq" . Your oil cooler inlet is ~24sq" and (at 1:1 ratio) = that would=20 leave only ~36sq"/2=3D18sq" for each rad inlet. Since they = seem larger=20 than that, how do you get by with the relatively small inlet to outlet=20 ratio, that is less that 1:1?

Does this question make = sense? I'm=20 trying to redesign my oulet size to a total of something larger than = inlet area=20 which I estimate at a total ~90sq"

ps. Would someone precisely = define=20 "pressure recovery" = for me?
