  2. Electronic cigarette - Wikipedia

    en.wikipedia.org/wiki/Electronic_cigarette

    An exploded view of a typical e-cigarette design with transparent atomizer (labeled clearomizer in diagram) and changeable dual-coil head. An electronic cigarette consists of an atomizer, a power source such as a battery, [25] and a container for e-liquid such as a cartridge or tank.

  3. Instant hot water dispenser - Wikipedia

    en.wikipedia.org/wiki/Instant_hot_water_dispenser

    A hot water dispenser which keeps water hot in a tank uses the energy needed to heat the water to the required temperature and wastes the energy needed to keep the water hot permanently in a thermally-insulated tank when not being used. These tank type dispensers often also consists of energy wasting 'keep warm' and 'reboil' functions.

  4. Volume correction factor - Wikipedia

    en.wikipedia.org/wiki/Volume_Correction_Factor

    That is, observed temperatures above 60 °F (or the base temperature used) typically correlate with a correction factor below "1", while temperatures below 60 °F correlate with a factor above "1". This concept lies in the basis for the kinetic theory of matter and thermal expansion of matter , which states as the temperature of a substance ...

  5. Flash evaporation - Wikipedia

    en.wikipedia.org/wiki/Flash_evaporation

    The water is heated and then routed into a reduced-pressure flash evaporation "stage" where some of the water flashes into steam. This steam is subsequently condensed into salt-free water. The residual salty liquid from that first stage is introduced into a second flash evaporation stage at a pressure lower than the first stage pressure.

  6. Jacketed vessel - Wikipedia

    en.wikipedia.org/wiki/Jacketed_vessel

    In chemical engineering, a jacketed vessel is a container that is designed for controlling temperature of its contents, by using a cooling or heating "jacket" around the vessel through which a cooling or heating fluid is circulated.

  7. Vapour pressure of water - Wikipedia

    en.wikipedia.org/wiki/Vapour_pressure_of_water

    The boiling point of water is the temperature at which the saturated vapor pressure equals the ambient pressure. Water supercooled below its normal freezing point has a higher vapor pressure than that of ice at the same temperature and is, thus, unstable. Calculations of the (saturation) vapor pressure of water are commonly used in meteorology.

  8. Vacuum evaporation - Wikipedia

    en.wikipedia.org/wiki/Vacuum_evaporation

    When the process is applied to food and the water is evaporated and removed, the food can be stored for long periods without spoiling. It is also used when boiling a substance at normal temperatures would chemically change the consistency of the product, such as egg whites coagulating when attempting to dehydrate the albumen into a powder.

  9. Vacuum insulated evaporator - Wikipedia

    en.wikipedia.org/wiki/Vacuum_insulated_evaporator

    Diagram showing the components of a VIE system. A photo showing a VIE system. A vacuum insulated evaporator (VIE) is a form of pressure vessel that allows the bulk storage of cryogenic liquids including oxygen, nitrogen and argon for industrial processes and medical applications.
