hydraulic drop
1Hydraulic 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… …
2Hydraulic 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… …
3Hydraulic 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… …
4Hydraulic analogy — The electronic–hydraulic analogy (derisively referred to as the drain pipe theory by Oliver Heaviside) is the most widely used analogy for electron fluid in a metal conductor. Since electric current is invisible and the processes at play in… …
5Hydraulic ram — A hydraulic ram is a cyclic water pump powered by hydropower. It functions as a hydraulic transformer that takes in water at one hydraulic head and flow rate, and outputs water at a different hydraulic head and flow rate. The device utilizes a… …
6Drop structure — A drop structure, also known as a grade control, sill, or weir, is a manmade structure, typically small and built on minor streams, or as part of a dam s spillway, to pass water to a lower elevation while controlling the energy and velocity of… …
7Drop tank — A 330 US gallons (1,200 L) Sargent Fletcher drop tank being moved across the flight deck of an Aircraft carrier In aeronautics, a drop tank (external tank, wing tank, or belly tank) is used to describe auxiliary fuel tanks externally carried …
8Gravity drop — refers to the use of gravity to deploy landing gear on an airplane in the event of hydraulic, engine, or power failure.The pilots activate a switch in the cockpit, which releases the lock of the gear door. Gravity then pulls the landing gear… …
9Frictional pressure drop — The frictional pressure drop is the decrease in pressure as a fluid passes through a conduit, caused by frictional losses within the conduit.This article was created to discuss merging the following articles: *Friction factor *Darcy friction… …
10Forging — This article is about the metalworking process. For specific hot forging hearth, see forge. For the act of counterfeiting, see forgery. Hot metal ingot being loaded into a hammer forge Forging is a manufacturing process involving the shaping of… …
