Hydraulics (from Ancient Greek ὕδωρ (húdōr) ' water ' and αὐλός (aulós) ' pipe ') [ 2] 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.
Hydraulic engineering is the application of the principles of fluid mechanics to problems dealing with the collection, storage, control, transport, regulation, measurement, and use of water. [ 1] Before beginning a hydraulic engineering project, one must figure out how much water is involved. The hydraulic engineer is concerned with the ...
The Parkland formula is mathematically expressed as: [ 4] where mass (m) is in kilograms (kg), area (A) as a percentage of total body surface area, and volume (V) is in milliliters (mL). For example, a person weighing 75 kg with burns to 20% of his or her body surface area would require 4 x 75 x 20 = 6,000 mL of fluid replacement within 24 ...
t. e. Pascal's law (also Pascal's principle[ 1][ 2][ 3] or the principle of transmission of fluid-pressure) is a principle in fluid mechanics given by Blaise Pascal that states that a pressure change at any point in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere. [ 4]
Applied mechanics is the branch of science concerned with the motion of any substance that can be experienced or perceived by humans without the help of instruments. [ 1] In short, when mechanics concepts surpass being theoretical and are applied and executed, general mechanics becomes applied mechanics. It is this stark difference that makes ...
In the Eulerian specification of a field, the field is represented as a function of position x and time t. For example, the flow velocity is represented by a function. On the other hand, in the Lagrangian specification, individual fluid parcels are followed through time. The fluid parcels are labelled by some (time-independent) vector field x0.
Jurin's law, or capillary rise, is the simplest analysis of capillary action —the induced motion of liquids in small channels [1] —and states that the maximum height of a liquid in a capillary tube is inversely proportional to the tube's diameter. Capillary action is one of the most common fluid mechanical effects explored in the field of ...
The most common leak detection method for pipeline operators is called the Supervisory Control And Data Acquisition (SCADA) system. This system uses a series of sensors to track data such as pressure, flow rates, temperature, and whether valves are open or closed.
