which of the black shapes is more affected by drag?
Bottom
>>993700
top actually.
frontal area matters but not having a "tail" causes more turbulence and drag.
>>993707
More drag than have a face perpendicular to the flow?
>>993711
The top shape has no pressure recovery and is carrying a huge low pressure vortex behind it - massive pressure drag.
Given equal front areas, the shape of the low-pressure side (the downstream side) matters much more. The lower shape has far less drag than the upper shape.

what would you say to this german?

>>993714
too bad we can't put the low-pressure side up front heh
>>993715
>>>/int/63429751
>>993718
Convinced me. As an uneducated onlooker I'm going to say the top shape is less affected by drag.
>>993732
then there's this
>>>/sci/8268804
Bottom, because neither is efficient at creating lift, the form drag from the front of the bottom and the fact that air is not viscous enough to remain laminer on the bottom is a double whammy.

how could i possibly deduce this on my own?
>>993698
they both fucking suck boi

What's the Reynold's number we are working with?
