Diffusion and thermal diffusion in some dilute binary

Limiting binary diffusion coefficients, D 0 12, for mixtures of He with Ar, O 2, N 2, CO 2 and SF 6 and of Ar with N 2 and O 2, determined by the two-bulb method, are reported for the temperature range 195–400 K.The apparatus, calibrated with absolute data obtained at 300 K with a Loschmidt cell, greatly extends the temperature range covered in this Laboratory, previously limited to 275

Henry''s law - Wikipedia

2019-4-20 · In chemistry, Henry''s law is a gas law that states that the amount of dissolved gas in a liquid is proportional to its partial pressure above the liquid. The proportionality factor is called Henry''s law constant. It was formulated by the English chemist William Henry, who studied the topic in the early 19th century. In his publiion about

Investigation on critical breakdown electric field of hot

2019-1-30 · Sulfur hexafluoride (SF6) gas, widely used in high-voltage circuit breakers, has a high global warming potential and hence substitutes are being sought. The use of a mixture of carbon tetrafluoride (CF4) and SF6 is examined here. It is known that this reduces the breakdown voltage at room temperature. However, the electrical breakdown in a circuit breaker after arc interruption occurs in a …

Atmospheric SF6: Trends, Sources, and Prospects

2018-2-5 · Sulfur hexafluoride (SF6) is the most potent greenhouse gas known. Its atmospheric concentration has increased by 2 orders of magnitude since industrial production started in 1953. Once released into the atmosphere, SF6 will only be removed exceedingly slowly due to its atmospheric lifetime of about 3200 yr. These features have brought SF6 into the climatic impact discussion aimed at …
