Overcome drag
WebApr 6, 2024 · O Aquatic animals that swim on the surface must overcome fewer sources of drag than animals that swim underwater. O The drag faced by most fish swimming underwater is much greater than previously thought. O All fish must overcome at least TWo forces of drag—the drag produced by their own bodies and by the bow wave. 3. WebDec 19, 2015 · The rest of the energy from the fuel (~ 65%) is lost on heating up the atmosphere directly, excess kinetic energy in the exhaust stream, internal drag & friction of the engine and producing noise. The remaining ~35% the energy is there to overcome the work done by drag. This drag can be split into lift induced drag and parasitic drag.

It’s the critical millimeters-thick volume of water right against a fish’s skin that causes drag. If the flow in this thin boundary layer becomes turbulent, Bruecker says the friction drag increases nearly five-fold.
