Dry Bulb, Wet Bulb and Dew Point Temperatures - The Engineering ToolBox
Constant dry bulb temperatures appear as vertical lines in the psychrometric chart or horizontal lines in the Mollier diagram. The Wet Bulb temperature is the adiabatic saturation temperature. Wet Bulb temperature can be measured by using a …
Air - Psychrometric Chart for Standard Atmospheric Conditions ...
The psychrometric chart below is made for standard atmospheric conditions. English (Imperial) units with wet bulb and dry bulb temperature and relative humidity; barometric pressure 29.921 inches of Mercury; dry bulb temperature ranging 20 o F to 120 o F; with enthalpy units in Btu/lb
Psychrometric Chart Use - Penn State Extension
2023年7月12日 · Wet-bulb temperature is located along diagonal dotted lines leading to scale readings at the upper, curved boundary marked "saturation temperature." The intersection of the vertical 78°F dry-bulb line and the diagonal 65°F wet-bulb line has now established a state point for the measured air.

Dry Bulb Temperature: 23.9°C (75°F) Wet Bulb Temperature: 10°C (50°F) Steps: 1. Plot the state point where the 23.9°C (75°F) vertical line and the 10°C (50°F) wet bulb line intersect. 2. Follow the wet bulb temperature line to the saturation curve. 3. Read the dry bulb temperature at the saturation point. 4. Cooling Effect:
the dry bulb temperature of 74oF and the wet bulb temperature of 62oF indicated by the psychrometer in Figure 386.1. First find the dry bulb temperature and draw a line straight up the chart. Next find the wet bulb temperature on the curved saturation line. This may take a …
Moist Air - Psychrometric Terms - The Engineering ToolBox
The Wet-Bulb Temperature and the Dry-Bulb Temperature will be identical with 100% relative humidity in the air (the air is at the saturation line). On the chart, the Wet-Bulb Temperature lines slopes a little upward to the left, and the temperature is read at the saturation line.
