  2. Thermal conductance and resistance - Wikipedia

    en.wikipedia.org/wiki/Thermal_conductance_and...

    Maximum temperature drop from junction to ambient = (+). We use the general principle that the temperature drop Δ T {\displaystyle \Delta T} across a given absolute thermal resistance R θ {\displaystyle R_{\theta }} with a given heat flow Q ˙ {\displaystyle {\dot {Q}}} through it is:

  3. Photovoltaic thermal hybrid solar collector - Wikipedia

    en.wikipedia.org/wiki/Photovoltaic_thermal...

    Significant research has gone into developing a diverse range of PVT technologies since the 1970s. [4] The different PVT collector technologies differ substantially in their collector design and heat transfer fluid and address different applications ranging from low temperature heat below ambient up to high temperature heat above 100 °C. [5]

  4. Cleanroom - Wikipedia

    en.wikipedia.org/wiki/Cleanroom

    The ambient outdoor air in a typical urban area contains 35,000,000 particles for each cubic meter in the size range 0.5 μm and bigger, equivalent to an ISO 9 certified cleanroom. By comparison, an ISO 14644 -1 level 1 certified cleanroom permits no particles in that size range, and just 12 particles for each cubic meter of 0.3 μm and smaller.

    The highest temperature ever recorded in Australia is 50.7 °C (123.3 °F), which was recorded on 2 January 1960 at Oodnadatta, South Australia, and 13 January 2022 at Onslow, Western Australia. The lowest temperature ever recorded in Australia is −23.0 °C (−9.4 °F), at Charlotte Pass, New South Wales , on 29 June 1994.

    The medals used for the 2020 Summer Olympics were designed by Junichi Kawanishi. [18] They were manufactured using metal extracted from recycled small electronic devices donated by the public. [ 18 ]

  8. Heat index - Wikipedia

    en.wikipedia.org/wiki/Heat_index

    A sustained wet-bulb temperature of about 35 °C (95 °F) can be fatal to healthy people; at this temperature our bodies switch from shedding heat to the environment, to gaining heat from it. [9] Thus a wet bulb temperature of 35 °C (95 °F) is the threshold beyond which the body is no longer able to adequately cool itself.

  9. Sea surface temperature - Wikipedia

    en.wikipedia.org/wiki/Sea_surface_temperature

    A wet-bulb temperature at 500 hPa in a tropical atmosphere of −13.2 °C (8.2 °F) is required to initiate convection if the water temperature is 26.5 °C (79.7 °F), and this temperature requirement increases or decreases proportionally by 1 °C in the sea surface temperature for each 1 °C change at 500 hpa.
