Question

what efforts would you do to drag the persons out of drag crises?​

Answer 1

Answer :

--------------

In fluid dynamics, drag crisis is a phenomenon in which drag coefficient drops off suddenly as Reynolds number increases. This has been well studied for round bodies like spheres and cylinders.

For larger objects (such as a baseball) moving at a velocity v in air, the drag force is given by FD=12CρAv2 F D = 1 2 C ρ A v 2 , where C is the drag coefficient (typical values are given in Table 1), A is the area of the object facing the fluid, and ρ is the fluid density.

In fluid dynamics, drag crisis (also known as the Eiffel paradox) is a phenomenon in which drag coefficient drops off suddenly as Reynolds number increases. ... This corresponds to the point where the flow pattern changes, leaving a narrower turbulent wake.
