A fluid by definition will not have a bulk modulus
since it will deform instantanuously and irreviersibly
when exposed to a shear. It will however, have a
viscosity which determines how much it will deform
when exposed to a shear. If it is viscoelastic it will
have both a storage (elastic) and loss (viscous)
modulus.
