Temp ratio
WebThe maximum temperature for which there is data is 500 deg.C. There is more detailed ‘typical’ data in the INCO publication ‘Austenitic chromium-nickel stainless steels-engineering properties at elevated temperatures’. WebBoth the specific humidity and the mixing ratio are highest around the equator at around 20 g kg-1, where the air is warm and can contain more water vapour, and lowest (near zero) in the cold polar regions and high in the atmosphere. Thermal humidity 'Dew point temperature' and 'wet bulb temperature' are also measures of humidity.
