when i get water flow length (Lw) from
Lw = (rh)*(Aw)/(Ac);
rh: hydraulic radius
Aw :total transfer area of water
Ac : free-flow area of water
it is the total flow length of water so if i have two rows per tube and 20 tube ,i divid it by 40 to get radiator horizontal width ?
OR it is the horizontal width dirctly ?
