According to the atmosphere page drag force is proportional to area, which is proportional to mass. So shouldn't two X200-16 tanks have the same mass and therefore the same drag as an X200-32? --einsteiner

KSP uses fixed drag values and doesn't calculate them. Because both tanks have a drag of 0.2, two smaller tanks generate twice the drag as one large tank.
Oh, and something about the "area is proportional to mass" thing: When talking about full tanks, that is sort of true. However, if you empty out the tank, it still has the same area, but is lighter. So area is actually not proportional to mass. In this specific case you would be correct though, two smaller tanks should have the same drag as one larger tank. --dgelessus (talk · contribs) 16:02, 27 August 2013 (CDT)
