On a diving forum I recently saw a comment on how the resistance of the water increases by 4 times when speed is doubled.
To verify the theory, I went in to www.3dcontentcentral.com and downloaded a diver in SolidWorks format.
Then I ran two tests in SolidWorks Flow Simulation.
The result was almost exactly 4 times difference in the power according to the theory.

Thanks for solving this problem Mattias. I was having a hard time explaining to my kids why it is harder to swim compared to running for a given speed. I wonder how the resistance is with air?
