That same question was in my science test! The answer is a siphon :D
the voltage at which electronic device operates is callled threshold voltageand the voltage at which device show cinduction in forward biased stste
electrical device
A device which operates(or function) only in one direction is called unidirectional (or unipolar) device
To make a suction device, you will need a container with a sealed top, a tube, and a way to create a pressure difference. One common method is to create a vacuum by sucking air out of the container using a pump or your mouth. As the air is removed, the pressure inside the container decreases, causing the outside air pressure to push the liquid up the tube and into the container. This creates suction, allowing you to pick up liquids or small objects.
Transducer (i.e. a device for converting energy from one form to another) for both vacuum and positive pressure.
A pressure sensing device commonly used in low pressure control systems is a diaphragm pressure switch. This device operates by detecting changes in pressure through a flexible diaphragm that triggers a switch mechanism at set pressure thresholds to activate or deactivate control functions such as turning a system on or off.
A mercury pressure device, such as a manometer, works based on the principle that the pressure of a fluid is directly proportional to the height of the fluid column. In a mercury manometer, a column of mercury is used to measure the pressure difference between two points. The difference in height of the mercury column indicates the pressure difference between the two points.

A Venturi meter works based on the principle of Bernoulli's equation, which states that an increase in fluid velocity results in a decrease in pressure. The Venturi meter is a device that measures the flow rate of a fluid by creating a pressure difference between two points in a pipe, allowing for flow rate calculations based on this pressure difference.
The amperage required for a device that operates at 7500 watts can be calculated by dividing the wattage by the voltage of the power source. If the device operates at 120 volts, the amperage required would be 62.5 amps.
To calibrate differential pressure, you will need a calibration instrument such as a pressure gauge or calibrator. Connect the instrument to the differential pressure device, apply a known pressure, and compare the readings from the device to the instrument. Adjust the device's output if necessary to match the known pressure applied for accurate calibration.
A device that operates on 220v typically requires a power cord with a voltage rating of 220v and a compatible plug type for the specific country or region where the device will be used.
Camshaft
the camshaft
The device that operates on 120V AC power requires a power cord with a standard 3-prong plug.
A Hogger is a device to remove the Air from Turbine inside for creating initial vaccume for start up the turbine means create negative pressure inside Turbine or say creates less pressure than atmospheric pressure in Turbine.An Ejector is a device used in Power plant to remove Undissolved gases from Condenser to avoid any harm to system from these gases.If any correction is required pl. correct it.
The maximum current rating for the circuit breaker needed for a device that operates at 20 amps is 25 amps.
