Point 2 shows the air being cooled to the dew point, that is where the relative humidity would reach 100% and a cloud would form. Then the air is cooled below the dew point, to 30 F. Point 3 shows the 30 F air can't hold the 7.5 g/kg of water vapor that was originally found in the air.

The Dew Point and the Role of Insulation | EcoRenov
As the moist air passes through the blown insulation or mattress, the temperature cools as it approaches the outside. It can eventually reach a point below the dew point, where moisture condenses inside the wall or in the attic, causing water and mold damages inside insulation.You should avoid this by minimizing the humidity flow in the wall, insulating well and performing good humidity ...
Distillation Tutorial I
Bubble and dew point temperature calculations are important because they make up part of the calculations embedded in distillation calculations. Find the bubble point of a 40-60 mol % mixture of ethylene and ethane at 300 psia. Find the dew point temperature and liquid composition for a 40-60 mol % mixture of ethylene and ethane at 300 psia.
Application Note Dew-point Calculation
Nov 18, 2001 · Definition of dew point: The dew-point temperature is the temperature to which the air must be cooled to reach saturation (assuming air pressure remains the same). When the temperature cools to the dew point, fog or dew can occur, and the relative humidity becomes 100%. Calculation of the dew point: The Magnus formula [Sonntag90] relates the ...

LATEST ADVANCES IN THE UNDERSTANDING OF ACID DEWPOINT
2 DEW POINTS OF H 2O, NO 2 AND SO 3 Based on data from literature, the dew points of various gas compositions can be calculated and plotted. The dew point is the temperature at which the first liquid starts to condense from the gas phase. The water dew point can be plotted from the water vapour pressures tables 1. Figure 1.

How to Choose the Right Instrument for Measuring Humidity and Dew Point
How to Choose the Right Instrument for Measuring Humidity and Dew Point Partial Pressure of Water Vapor Humidity is simply water in its gaseous phase, properly called water vapor. Because water vapor is a gas, most of the common gas laws apply to it
The Station Model: Part I | METEO 3: Introductory Meteorology
The higher the concentration of water vapor, the higher the dew point, and as such, the dew point affects the way the air "feels" - whether it be dry or muggy. Since our skin temperature is regulated to some degree by evaporation of sweat, it would be logical that we would be affected to some degree by the dew point temperature.

measured droplet dew point in Figure 5. The SRK calculated dew point given in RR-196 agrees slightly better with the manual droplet dew point than does the Ametek automated dew point which was tuned to the iridescent ring. As previously stated, the iridescent ring method should give higher dew point values than the droplet method.

DOC) Calculating Bubble & Dew Points for Ideal Mixtures P
The dew point is the point at which the first drop of a gaseous mixture begins to condense.For a pure component, the bubble and dew point are both at the same temperature -its boiling point. For example, pure water will boil at a single temperature (at atmospheric pressure, this is 100 o C).For ideal mixtures (i.e. mixtures where there are no ...
What is Dew Point? - 1 Stop Landscape Supply
Essentially, dew point is defined as the temperature that, under the right conditions, will produce condensation. NOAA’s National Weather Service , defines it as the “temperature the air needs to be cooled to (at constant pressure) in order to achieve a relative humidity (RH) of 100%.
