hydrodynamicsn.

/ˌhʌɪdrə(ʊ)dʌɪˈnamɪks/

/ˌhʌɪdrə(ʊ)dɪˈnamɪks/

Etymology: < modern Latin hydrodynamica: see hydro- comb. form 1 and dynamics n. Compare French hydrodynamique. The Latin word appears in a treatise by Daniel Bernoulli, 1738, entitled ‘Hydrodynamica, sive de viribus et motibus fluidorum commentarii’.

The branch of Physics which treats of the forces acting upon or exerted by liquids. In earlier use = hydrokinetics n.; now usually taken in a comprehensive sense to include Hydrokinetics and Hydrostatics; but the earlier usage is still retained by some physicists. (Cf. dynamics n.)
