  2. Anemometer - Wikipedia

    en.wikipedia.org/wiki/Anemometer

    Hot wire anemometers use a fine wire (on the order of several micrometres) electrically heated to some temperature above the ambient. Air flowing past the wire cools the wire. As the electrical resistance of most metals is dependent upon the temperature of the metal ( tungsten is a popular choice for hot-wires), a relationship can be obtained ...

  3. Thermal mass flow meter - Wikipedia

    en.wikipedia.org/wiki/Thermal_mass_flow_meter

    The operation of thermal dispersion mass flow meters is attributed to L.V. King who, in 1914, published his famous King's Law revealing how a heated wire immersed in a fluid flow measures the mass velocity at a point in the flow. King called his instrument a "hot-wire anemometer".

  4. Particle image velocimetry - Wikipedia

    en.wikipedia.org/wiki/Particle_image_velocimetry

    Particle image velocimetry (PIV) is a non-intrusive optical flow measurement technique used to study fluid flow patterns and velocities. PIV has found widespread applications in various fields of science and engineering, including aerodynamics, combustion, oceanography, and biofluids.

  5. Hotwire - Wikipedia

    en.wikipedia.org/wiki/Hotwire

    Hot-wiring, a method of starting a car with no key; Hot-wire foam cutter, a tool used to cut foam and polystyrene; Hot wire (electricity), a wire conductor with non-zero potential in electric power distribution; Hot-wire anemometer, an electrical device for measuring the speed of airflow

  6. Mass flow sensor - Wikipedia

    en.wikipedia.org/wiki/Mass_flow_sensor

    The theory of operation of the hot wire mass airflow sensor is similar to that of the hot wire anemometer (which determines air velocity). This is achieved by heating a wire suspended in the engine's air stream, like a toaster wire, by applying a constant voltage over the wire.

  7. Wind speed - Wikipedia

    en.wikipedia.org/wiki/Wind_speed

    The anemometer was mounted 10 m above ground level (and thus 64 m above sea level). During the cyclone, several extreme gusts of greater than 83 m/s (300 km/h; 190 mph; 161 kn; 270 ft/s) were recorded, with a maximum 5-minute mean speed of 49 m/s (180 km/h; 110 mph; 95 kn; 160 ft/s); the extreme gust factor was on the order of 2.27–2.75 times ...

    Waving flags. Homemade signs. Most importantly, fans that hung (and screamed) on every play, every call, every goal. This was a scene. This was intense.

  9. Wollaston wire - Wikipedia

    en.wikipedia.org/wiki/Wollaston_wire

    The wire is named after its inventor, William Hyde Wollaston, who first produced it in England in the early 19th century. [1] Platinum wire is drawn through successively smaller dies until it is about 0.003 inches (0.076 mm, 40 AWG) in diameter. It is then embedded in the middle of a silver wire having a diameter of about 0.100 inches (2.5 mm ...
