The hydraulic analogy compares electric current flowing through circuits to water flowing through pipes.

In a hydraulic analogy, passing current through a high-resistivity material is like pushing water through a pipe full of sand, while passing current through a low-resistivity material is like pushing water through an empty pipe.

This work is an hydraulic analogy of shock wave cancellation in gas, allowing to consider the possibility of supersonic cruise in dense air without any sonic boom.

Considering the " filter " action, a better and more exact analogy is the hydraulic accumulator " pressure tank ", as described, but with a closed, pressurized air bladder and only one water connection.

The bay was navigable as far south as San Jose until the 1850s, when hydraulic mining released massive amounts of sediment from the rivers that settled in those parts of the bay that had little or no current.

A key figure in this story is city architect Nicolaas Plomp, who, besides his work for the current IJssel front of the city of Kampen, was also involved in hydraulic engineering.

The Ludwig brothers developed a hydraulic action timpani and in 1916 invented a spring mechanism — the basis for the current Balanced Action Pedal Timpani.

It is operated by a source of energy, usually in the form of an electric current, hydraulic fluid pressure or pneumatic pressure, and converts that energy into some kind of motion.

A tidal bore is a hydraulic jump which occurs when the incoming tide forms a wave ( or waves ) of water that travel up a river or narrow bay against the direction of the current.

The hydraulic pressure controlled by these valves drives the various clutch and brake band actuators, thereby controlling the operation of the planetary gearset to select the optimum gear ratio for the current operating conditions.

In this case a hydraulic control unit with a pressurized storage tank provides the force to rapidly insert the control rods upon any interruption of the electric current, again within four seconds.

The current fleet consists of 70 diesel-electric 3000 / 3100 railcars and 29 2000 / 2100 diesel hydraulic railcars.

The construction of the Marly hydraulic machine, actually located in Bougival ( where his inventor Rennequin Sualem died in 1708 ), driven by the current of the Seine moving fourteen vast paddlewheels, was a miracle of modern hydraulic engineering, perhaps the largest integrated machine of the 17th century.

Most systems employ eddy current, oil hydraulic, or DC motor produced loads because of their linear and quick load change abilities.

Specialising in hydraulic loading cranes in 1964, his son Hubert laid the foundation stone of the current company.

The Ludwig brothers next developed a hydraulic action timpani and in 1916 invented a spring mechanism — the basis for the current Balanced Action Pedal Timpani.

In this device, the flow of pressurized hydraulic fluid drives a reciprocating piston supported by three piezoelectric elements which convert the pressure fluctuations into an alternating current.

Drive is from a direct current electric motor and universal hydraulic speed gears ( a manual mechanical drive is also provided in case of electrohydraulic failure ; with the use of mechanical drive, elevation speed is 4. 5 ° per second and the turret traverse speed is 4 ° per second ).

Since electric current is invisible and the processes at play in electronics are often difficult to demonstrate, the various electronic components are represented by hydraulic equivalents.

Electricity ( as well as heat ) was originally understood to be a kind of fluid, and the names of certain electric quantities ( such as current ) are derived from hydraulic equivalents.

This means that rills exhibit very different hydraulic physics than water flowing through the deeper, wider channels of streams and rivers.

Standing waves and hydraulic jumps also form on fast flowing river rapids and tidal currents such as the Saltstraumen maelstrom.

A hydraulic fill is an embankment or other fill in which the materials are deposited in place by a flowing stream of water, with the deposition being selective.

* The stationary hydraulic jump – rapidly flowing water transitions in a stationary jump to slowly moving water as shown in Figures 1 and 2.

Its concept is similar to the modern hydraulic ram, which also uses the power of flowing water to pump some of the water out of the river.

After flowing over the mountain, a type of shock wave forms at the trough of the flow, and a sharp vertical discontinuity called the hydraulic jump forms which can be several times higher than the mountain.

The Valkyrie engine is based on the Gold Wing engine, but has solid lifters instead of hydraulic lifters, six carburetors instead of the Gold Wing's two, more aggressive camshafts, a free flowing exhaust, and altered ignition timing to increase performance.

; Current: Equivalent to a hydraulic volume flow rate ; that is, the volumetric quantity of flowing water over time.

* Wood's Ferry ( Class IV +-a shallow rapid with large ledge pour-overs on river-left, " PJ's Hole " just right of center, and at the bottom, " Julie's Juicer ", a twisting hydraulic flowing off the left side of a large rock in the center of the river.

The pieces are carefully heated with exclusion of air and then compressed into a uniform mass by intense hydraulic pressure ; the softened amber being forced through holes in a metal plate.

No pressure on the lever means that the clutch plates are engaged ( driving ), while pulling the lever back towards the rider will disengage the clutch plates through cable or hydraulic actuation, allowing the rider to shift gears or coast.

Mechanical and hydro-mechanical flight control systems are relatively heavy and require careful routing of flight control cables through the aircraft by systems of pulleys, cranks, tension cables and hydraulic pipes.

A pressure vessel containing air cushions the hydraulic pressure shock when the waste valve closes, and it also improves the pumping efficiency by allowing a more constant flow through the delivery pipe.

As the cooling system was almost invariably placed where direct fire wouldn't hit them, the target of choice was the rear deck of a tank ; the burning contents of the bottle would pour through the large cooling grills and ignite fuel, hydraulic fluids and ammunition.

* Permeability is the rate in which water flows, and this is measured in gallons per day through a one square foot cross section under a unit hydraulic gradient.

* Circuit theory, the theory of accomplishing work by routing electrons, gas, fluids, or other matter through loops ( e. g., electrical, hydraulic or pneumatic circuits )

The gun rotor, barrel assembly and ammunition feed system are rotated by a hydraulic drive motor through a system of flexible drive shafts.

The power created is transmitted through a gearbox to drive an electrical generator and hydraulic pump.

His inventions include the hydraulic press, which multiplied a smaller force acting on a larger area into the application of a larger force totaled over a smaller area, transmitted through the same pressure ( or same change of pressure ) at both locations.

Most MUs are powered either by traction motors, receiving their power through a live rail or overhead wire ( EMU ), or by a diesel engine driving the wheels through a gearbox or hydraulic transmission ( DMU ).
