We know that volumetric elasticity is a reciprocal of compressibility. Since air is more compressible than Water that is why water is more elastic then air.

Dimensional analysis proof of Stokes' Law Suppose that the sphere has radius r and falls through a fluid of viscosity η. Let the terminal velocity be v We can calculate the viscous drag F on the sphere by dimensional analysis. If F = krxηyvz We have MLT-2 = Lx(ML-1T-1)y(LT- 1)z Solving this gives x = 1, y = 1 and z = 1. By other methods k can be shown to be 6π. Thus giving: F = 6πηrv

It is called the zeroth law because it came to light after the first and second laws of thermodynamics had already been established and named, but was considered more fundamental and thus was given a lower number zero.
