Webvapour to the air stream at the same time as it cools it, is the basis for psychrometry and many other microclimatic phenomena. Control of heat transfer can be used to control the drying and wetting of materials during conservation treatment. The enthalpy of dry air is not known. Air at zero degrees celsius is defined to have zero enthalpy. WebThe final condition of the mixture can be found with the help of chart as follows: First determine the percentage of air in each stream, in the mixture. Let in stream one, this is x%. Therefore, (100 – x) is the percentage of air mass in other stream. Then locate the two points 1 and 2 from the given conditions of two streams.
