Water pressure may fail or be reduced when a water main bursts, pipes freeze, or there is unexpectedly high demand on the water system (for example, when several fire hydrants are opened). Reduced pressure in the pipe may allow contaminated water from the soil , from storage, or from other sources to be drawn up into the system.
A common dual dimmer module used in stage lighting A dimmer. A dimmer is a device connected to a light fixture and used to lower the brightness of the light.By changing the voltage waveform applied to the lamp, it is possible to lower the intensity of the light output.
A cold cathode is distinguished from a hot cathode that is heated to induce thermionic emission of electrons. Discharge tubes with hot cathodes have an envelope filled with low-pressure gas and containing two electrodes. Hot cathode devices include common vacuum tubes, fluorescent lamps, high-pressure discharge lamps and vacuum fluorescent ...
When the temperature drops rapidly, within approximately 12 to 48 hours, water that has collected below the ground's surface freezes solid and expands quickly. This change cracks the ground ...
A street lamp mounted on a bracket and column A high pressure sodium street light fixture. Street light interference, sometimes called high voltage syndrome, is the claimed ability of individuals to turn street lights or outside building security lights on or off when passing near them. [1]
Freezing drizzle is extremely dangerous to aircraft in icing conditions, as the supercooled water droplets will freeze onto the airframe, degrading aircraft performance considerably. The loss and accident of American Eagle Flight 4184 on October 31, 1994, has been attributed to ice buildup due to freezing drizzle aloft.
