Determine dew point in wall assembly
WebDew point is defined as the temperature at which a given volume of air at a certain atmospheric pressure is saturated with water vapor, causing condensation and the formation of dew. Dew is the condensed water that a person often sees on flowers and grass early in the morning. Dew point varies depending on the amount of water vapor present in ... WebWith the conditions described beiow, determine if a recessed vapour placed in the wall assembly would be at risk of having water vapour condense on its surface. Steps to solve this problem With the inside temperature given on the wall assembly and an interior RH of 40% , calculate the dew point temperature of the airfyapour mixture.
