• Hydraulic machinery — are machines and tools which use fluid power to do work. Heavy equipment is a common example.In this type of machine, high pressure hydraulic fluid is transmitted throughout the machine to various hydraulic motors and hydraulic cylinders. The… …   Wikipedia

• Hydraulic head — is a specific measurement of water pressure or total energy per unit weight above a geodetic datum. It is usually measured as a water surface elevation, expressed in units of length, but represents the energy at the entrance (or bottom) of a… …   Wikipedia

• Hydraulic conductivity — Hydraulic conductivity, symbolically represented as K, is a property of vascular plants, soil or rock, that describes the ease with which water can move through pore spaces or fractures. It depends on the intrinsic permeability of the material… …   Wikipedia

• 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, levees, elevators, and to both sanitary …   Wikipedia

• Hydraulic fracturing — is a method used to create fractures that extend from a borehole into rock formations, which are typically maintained by a proppant. The method is informally called fracing or hydrofrac. The technique is used to increase or restore the rate which …   Wikipedia

• Flow measurement — is the quantification of bulk fluid movement. Flow can be measured in a variety of ways. Positive displacement flow meters acumulate a fixed volume of fluid and then count the number of times the volume is filled to measure flow. Other flow… …   Wikipedia

• Hydraulic clearance — Hydraulic clearance. Flow in narrow clearances are of vital importance in hydraulic system component design. The flow in a narrow circular clearance of a spool valve can be calculated according to the formula below if the height is negligible… …   Wikipedia

• Hydraulic tomography — (HT) is a sequential cross hole hydraulic test followed by inversion of all the data to map the spatial distribution of aquifer hydraulic properties. Specifically, HT involves installation of multiple wells in an aquifer, which are partitioned… …   Wikipedia

• Hydraulic Fracturing — refers to the procedure of creating fractures in rocks and rock formations by injecting a mixture of sand and water into the cracks to force underground to open further. The larger fissures allow more oil and gas to flow out of the formation and… …   Investment dictionary

• Hydraulic jump — A hydraulic jump is a phenomenon in the science of hydraulics which is frequently observed in open channel flow such as rivers and spillways. When liquid at high velocity discharges into a zone of lower velocity, a rather abrupt rise (a step or… …   Wikipedia
