Hydraulics Hydraulics Fire sprinklers are a fire supression system that consist of overhead pipes fitted with sprinkler heads throughout the coverage area. Fire sprinkler systems for high-rises are usually also equipped with a fire pump, and a jockey pump and are tied into the fire alarm system. Although historically only used in factories and large commercial buildings, home and small building systems are now available at a relatively cost-effective price. ...more on Wikipedia about "Fire sprinkler"
Fluid pressure is the pressure on an object submerged in a fluid, such as water. The pressure can be provided from a number of sources: ...more on Wikipedia about "Fluid pressure"
The Hazen-Williams formula can be used to calculate the pressure drop in a length of pipe due to friction dependent on the flow. It is a useful equation for pressure drop calculations in an american fire sprinkler or water distribution system. ...more on Wikipedia about "Hazen-Williams equation"
Head pressure is another term for the discharge pressure of the compressor in refrigeration and air conditioning systems. The head pressure is the pressure of the refrigerant in vapor form as it is discharged into the condenser. Several factors effect head pressure, such as cleanliness of the condenser coil, ambient temperature, and the size and speed of the condenser fan. ...more on Wikipedia about "Head pressure"
Heron's fountain is a hydraulic machine invented by the first century inventor, mathematician, and physicist Heron, also known as Hero of Alexandria. ...more on Wikipedia about "Heron's fountain"
Hydraulic engineering is a sub-discipline of civil engineering concerned with the flow and conveyance of fluids, principally water. This area of engineering is intimately related to the design of bridges, dams, channels, canals, and levees, and to both sanitary and environmental engineering. ...more on Wikipedia about "Hydraulic engineering"
Hydraulics is a branch of science and engineering concerned with the mechanical properties of liquids. It is part of the more general discipline of fluid power. The word "hydraulics" comes from the Greek word ὑδϱαυλικός (hydraulikos) which in turn comes from ὕδϱαυλος meaning water organ which in turn comes from ὕδωϱ ( water) and αὐλός ( pipe). The earliest masters of this art were Hero of Alexandria and Ctesibius. The ancient engineers however focused on sacral and novelty uses of hydraulics, rather than practical applications. One of the founders of modern hydraulics was Benedetto Castelli, a student of Galileo Galilei. ...more on Wikipedia about "Hydraulics"
In atmospheric dynamics and fluid dynamics, a hydrostatic fluid is a fluid in which fluid stresses act isotropically and fluid elements are in local equilibrium with one another. Thus, all directional fluid stresses, normally represented as vectors, can be summarized by a scalar quantity called the hydrostatic pressure, which can still depend on position. ...more on Wikipedia about "Hydrostatic fluid"
NPSH is an acronym for Net Positive Suction Head. It shows the difference, in any crosssection of a generic hydraulic circuit, between the pressure and the liquid vapor pressure in that section. ...more on Wikipedia about "NPSH"
A pressure vessel is a structure designed to contain a fluid at a different pressure to the pressure surrounding the structure without changing volume. ...more on Wikipedia about "Pressure vessel"
Transient flow is such a flow where the velocity and pressure changes over time. Transient flows usually occurs during the starting or stopping of a pump, the opening or closing of a tank, or simple changes in tank levels. Transient flow usually refers to surge or water hammer. The main reason why transient flow can be a problem is it can cause pressure that would exceed the limits of pipes, fittings, ect. ...more on Wikipedia about "Transient flow"
A water supply network is a system of engineered hydrologic and hydraulic components, including: ...more on Wikipedia about "Water supply network"
