The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa ), which is equivalent to 1,013.25 millibars, [1] 760 mm Hg, 29.9212 inches Hg, or 14.696 psi. [2] The atm unit is roughly equivalent to the mean sea-level atmospheric pressure on Earth; that is, the Earth's atmospheric pressure at sea level is ...

Atmospheric crude distillation unit. Crude oil must first be desalted, by heating to a temperature of 100-150 °C and mixing with 4-10% fresh water to dilute the salt. Crude oil exits from the desalter at a temperature of 250 °C–260 °C and is further heated by a tube-still heater to a temperature of 350 °C–360 °C.

In March 2014, Lellouch, de Bergh et al. published findings regarding methane mixing ratios in Pluto's atmosphere consistent with a Plutonian diameter greater than 2,360 km, with a "best guess" of 2,368 km. On July 13, 2015, images from NASA's New Horizons mission Long Range Reconnaissance Imager (LORRI), along with data from the other ...
