    • n Hydrodynamics That branch of the science of mechanics which relates to fluids, or, as usually limited, which treats of the laws of motion and action of nonelastic fluids, whether as investigated mathematically, or by observation and experiment; the principles of dynamics, as applied to water and other fluids.☞ The word is sometimes used as a general term, including both hydrostatics and hydraulics, together with pneumatics and acoustics. See Hydraulics.

    • n hydrodynamics The mathematical theory of the application of the principles of dynamics to fluids. As dynamics is used in two senses, the wider to include the theories both of rest and of motion, the narrower to include only the theory of motion, there are two corresponding senses of the word hydrodynamics. See dynamics. Also called hydrokinetics.
