I had so much fun creating graphs for the Red Bull Stratos ... v is the magnitude of the velocity of the object The direction of this air resistance force is in the opposite direction as the ...
This is because a low Reynolds number implies a time-reversible flow: changing the sign of time is equivalent to changing the sign of the velocity, and this gives exactly the same flow in the pipe but ...
