Eli5: How do they effectively test scale models of giant ships in water? Doesn’t the water behave differently in the small vs large scale?
In: Physics
A supplementary question would be if using a liquid with a lower viscosity than water assist in adjusting for the issues of scaling?
Acetone for instance has a viscosity of .36 that of water. Leaving aside the practical limitations, would this be a more suitable liquid for modelling at a smaller scale?
