(physics) The state in which a solid or liquid body has relaxed into the shape that it would have if it were a calm (equilibrium) liquid. Mathematically, this means a sphere if it is not distorted by another body and is not rotating, but an oblate or scalene ellipsoid if rotating moderately, and piriform if rotating beyond the ellipsoidal limit. When in contact with another object, such as oil drops on or in water, other shapes occur.

(mechanical engineering, usually uncountable) A condition that arises when a device which compresses gases seizes up because of the infiltration of liquid, which prevents further compression.

To seize up because liquid has infiltrated a mechanism for compressing gasses. / To form a seal by employing a mechanism that uses hydrostatic pressure.
