A sluice gate is traditionally a wood or metal barrier sliding in grooves that are set in the sides of the waterway. Sluice gates commonly control water levels and flow rates in rivers and canals. ... File Video 1,386- 2017 REMEMBER WATER MATTERS!

If the object has an irregular shape , the volume can be measured using a displacement can . The displacement can is filled with water above a narrow spout and allowed to drain until the water is level with the spout. As the irregular object is lowered into the displacement can, the water level rises.

In addition to helping farmers, dams help prevent the loss of life and property caused by flooding. Flood control dams impound floodwaters and then either release them under control to the river below the dam or store or divert the water for other uses.

Earth contains water in many places, and as dam prevents flooding, earth controls water. Water extinguishes fire, and therefore, controls its spread. Fire controls metal by its ability to melt it.

The Iroquois Dam, Moses-Saunders Power Dam, Long Sault Dam and the Eisenhower and Snell Navigation Locks contribute to the control of lake levels. The main control structure, Moses- Saunders Powers Dam, has the capacity to discharge 333,000 cfs of water from Lake Ontario in the St. Lawrence River.

noun. an artificial channel for conducting water, often fitted with a gate (sluice gate) at the upper end for regulating the flow. the body of water held back or controlled by a sluice gate.

Earth dikes and dams are gravity structures used to impound water or semi-fluid wastes. Water is impounded for flood control, hydroelectric power production, recreation, domestic storage, and industrial uses, including waste storage.

Aqueducts required a great deal of planning. They were made from a series of pipes, tunnels, canals, and bridges. Gravity and the natural slope of the land allowed aqueducts to channel water from a freshwater source, such as a lake or spring, to a city.

Sprinkler heads are equipped with a glass trigger filled with a glycerin-based liquid that expands with temperature. As the liquid expands, it breaks the glass and activated the sprinkler head. These sprinkler heads are attached to a reliable system of water pipes that are typically built into the walls or ceiling.

Governing system or governor is the main controller of the hydraulic turbine. The governor varies the water flow through the turbine to control its speed or power output. Generating units speed and system frequency may be adjusted by the governor.

SuDS can be designed to transport (convey) surface water, slow runoff down (attenuate) before it enters watercourses, they provide areas to store water in natural contours and can be used to allow water to soak (infiltrate) into the ground or evaporated from surface water and lost or transpired from vegetation (known ...

Minimum Flow or Automatic Recirculation Valves automatically protect centrifugal pumps during low load operation. As the pump's load drops below a preset flow rate, the valve's disc moves towards it's seat and causes the bypass bush to open a bypass flow path. The pump minimum flow rate is thus reached and maintained.

Surface currents in the ocean are driven by global wind systems that are fueled by energy from the sun. Patterns of surface currents are determined by wind direction, Coriolis forces from the Earth's rotation, and the position of landforms that interact with the currents.

2 spool hydraulic valve is a device used to control hydraulic systems. ... 2 spool hydraulic valve can manage the flow of hydraulic fluid from a hydraulic pump to an actuator. It can be open or closed, blocking of the route the fluid takes. The build of 2 spool hydraulic valve is simple.

Dikes used to hold back water are usually made of earth. ... When constructed along river banks, dikes control the flow of water. By preventing flooding, dikes force the river to flow more quickly and with greater force.

Vortex flow meters operate under the vortex shedding principle, where an oscillating vortexes occur when a fluid such as water flow past a bluff (as opposed to streamlined) body. The frequency that the vortexes are shed depend on the size and shape of the body.
