HydrostaticsFluid statics or hydrostatics is the branch of fluid mechanics that studies the condition of the equilibrium of a floating body and submerged body "fluids at hydrostatic equilibrium and the pressure in a fluid, or exerted by a fluid, on an immersed body". It encompasses the study of the conditions under which fluids are at rest in stable equilibrium as opposed to fluid dynamics, the study of fluids in motion. Hydrostatics is a subcategory of fluid statics, which is the study of all fluids, both compressible or incompressible, at rest.
Ancient Roman engineeringThe ancient Romans were famous for their advanced engineering accomplishments. Technology for bringing running water into cities was developed in the east, but transformed by the Romans into a technology inconceivable in Greece. The architecture used in Rome was strongly influenced by Greek and Etruscan sources. Roman roads Roads were common at that time, but the Romans improved their design and perfected the construction to the extent that many of their roads are still in use today.
ReservoirA reservoir (ˈrɛzərvwɑːr; from French réservoir ʁezɛʁvwaʁ) is an enlarged lake behind a dam. Such a dam may be either artificial, usually built to store fresh water, or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, excavating, or building any number of retaining walls or levees.
ThermaeIn ancient Rome, thermae (from Greek θερμός , "hot") and balneae (from Greek βαλανεῖον ) were facilities for bathing. Thermae usually refers to the large imperial bath complexes, while balneae were smaller-scale facilities, public or private, that existed in great numbers throughout Rome. Most Roman cities had at least one – if not many – such buildings, which were centers not only for bathing, but socializing and reading as well. Bathhouses were also provided for wealthy private villas, town houses, and forts.
HydraulicsHydraulics () is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on applied engineering using the properties of fluids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of power by the use of pressurized liquids.
NîmesNîmes (niːm , nim; Nimes ˈnimes; Latin: Nemausus) is the prefecture of the Gard department in the Occitanie region of Southern France. Located between the Mediterranean Sea and Cévennes, the commune of Nîmes has an estimated population of 148,561 (2019). Dubbed the most Roman city outside Italy, Nîmes has a rich history dating back to the Roman Empire when the city had a population of 50,000–60,000 and was the regional capital. Several famous monuments are in Nîmes, such as the Arena of Nîmes and the Maison Carrée.
Pont du GardThe Pont du Gard is an ancient Roman aqueduct bridge built in the first century AD to carry water over to the Roman colony of Nemausus (Nîmes). It crosses the river Gardon near the town of Vers-Pont-du-Gard in southern France. The Pont du Gard is the tallest of all Roman aqueduct bridges, as well as one of the best preserved. It was added to UNESCO's list of World Heritage sites in 1985 because of its exceptional preservation, historical importance, and architectural ingenuity.
