A Talk Aboyt Hydraulics.
We frequently hear people talk promiscuously about and get all mixed up in the use of the terms hydraulic, hydrostatic, hydrodynamics, etc., allowing to a misunderstanding or an ignorance of the proper meaning of these terms, says James F. Hobart, in an article in The Tradesman. This awkwardness would be avoided if it would always be remembered that hydraulics means the science which treats of liquids in motion, while hydrostatic only has to do with fluids while standing still. Hydrodynamics is a sort of a union term, and covers both the above. In other words, hydrodynamics is the science which treats of the phenomena of water or other fluids at rest or in motion.
Hydrodynamics treats only of fluids which are inelastic like water; the elastic fluids like air, steam, etc., cannot be studied under the title of hydrodynamics, they must take their turns under hydraulics and hydrostatics.
