Executed example of a Heron's fountain in operation. Heron's fountain is a hydraulic machine invented by the 1st century AD inventor, mathematician, and physicist Heron (or Hero) of Alexandria. [1] Heron studied the pressure of air and steam, described the first steam engine, and built toys that would spurt water, one of them known as Heron's ...
Phillips Machine in the Science Museum, London. The Phillips Machine, also known as the MONIAC (Monetary National Income Analogue Computer), Phillips Hydraulic Computer and the Financephalograph, is an analogue computer which uses fluidic logic to model the workings of an economy.

Hydraulic fuses are in-line safety devices designed to automatically seal off a hydraulic line if pressure becomes too low, or safely vent fluid if pressure becomes too high. Auxiliary valves in complex hydraulic systems may have auxiliary valve blocks to handle various duties unseen to the operator, such as accumulator charging, cooling fan ...
Devices placed on the top plate can be moved in the six degrees of freedom in which it is possible for a freely-suspended body to move: three linear movements x, y, z (lateral, longitudinal, and vertical), and the three rotations (pitch, roll, and yaw).
The screw pump is the oldest positive displacement pump. [1] The first records of a water screw, or screw pump, date back to Hellenistic Egypt before the 3rd century BC. [1] [3] The Egyptian screw, used to lift water from the Nile, was composed of tubes wound round a cylinder; as the entire unit rotates, water is lifted within the spiral tube to the higher elevation.
Illustration of hydraulic and hydrostatic, from the "Table of Hydraulics and Hydrostatics", from Cyclopædia, or an Universal Dictionary of Arts and Sciences, edited by Ephraim Chambers, 1728, Vol. 1. Hydraulics (from Ancient Greek ὕδωρ (húdōr) 'water' and αὐλός (aulós) 'pipe') [2] is a technology and applied science using ...
The hydraulic engineer is concerned with the transport of sediment by the river, the interaction of the water with its alluvial boundary, and the occurrence of scour and deposition. [1] "The hydraulic engineer actually develops conceptual designs for the various features which interact with water such as spillways and outlet works for dams ...
