What is the max speed an object can sink in water?

647 views

Like terminal velocity of an object falling in the air, is there the same said type terminal velocity for objects sinking in water? If so, how deep would an object have to be sinking in order to reach the speed? Does the weight of the object in water affect the speed as well?

The simple but unsatisfying answer is “the terminal velocity of that object in water”.

Terminal velocity in air is not a universal constant. Humans terminal velocity is something like 150 mph if they’re in the skydiving flat pose and up to about double that in the “pencil” pose. Feathers are more like 2 mph. The SR-71 in an unpowered dive probably very near the speed of sound.

Terminal velocity for all those objects in water would be probably an order of magnitude smaller, but still unequal to each other.
