Hydraulics

[technoguy]

Hydraulics is a science and engineering subject dealing with the mechanical properties of liquids. Hydraulics is part of the more general discipline of fluid power. The word "hydraulics" originates from the Greek word ὑδϱαυλικός (hydraulikos) which in turn orginates from ὕδϱαυλος meaning water organ which in turn comes from ὕδϱω (water) and αὐλός (pipe). The earliest masters of this art were Hero of Alexandria and Ctesibius. The ancient engineers focused on sacral and novelty uses of hydraulics, rather than practical applications. Ancient Sinhalese used hydraulics in many applications, in the Ancient kingdoms of Anuradhapura, Polonnaruwa etc
