- Mixing of Humid Air - The Engineering ToolBox
1 m 3 of air at 25 o C and 50% relative humidity (C) is mixed with 1 m 3 air at-5 o C and 80% relative humidity (A) From the Mollier diagram the humidity ratio of (C) is 0 0097 kg kg The enthalpy is 50 kJ kg The humidity ratio of (A) is 0 002 kg kg The enthalpy is 0 kJ kg The humidity ratio of the mixture can be calculated like
- Air Mixing Calculator | adicot. com
Example: Suppose you want to calculate the mixed air temperature of three air streams: Outdoor Air: 150 CFM @ 91oF Dry Bulb 77oF Wet Bulb Return Air: 1550 CFM @ 75oF Dry Bulb 62 3oF Wet Bulb Bypass Air: 300 CFM @ 55oF Dry Bulb 54 5oF Wet Bulb Calculate the Dry Bulb Mixed Air Temperature: TMA, DB = 91oF x 150 CFM + 75oF x 1550 CMF + 55oF x 300 CFM = 73 20oF Dry Bulb
- Mixed Air Calculator
Mixed air refers to the stream of air that results from combining two separate streams of air with different properties, such as temperature, humidity, and flow rate The resulting mixture of air will have unique properties that depend on the properties of the original streams and the proportion in which they were mixed
- Air - Heating, Cooling, Mixing, Humidifying or Dehumidifying Processes
Psychrometric chart to analyze air properties, including temperature, humidity, enthalpy, and dew point at barometric pressure 29 921 inches of Mercury and temperature ranging 20 o F to 120 o F Air and Steam Mixtures
- Air - Humidity Ratio - The Engineering ToolBox
The maximum amount of water vapor in the air is achieved when p w = p ws the saturation pressure of water vapor at the actual temperature (2) can be modified to: x s = 0 62198 p ws (p a - p ws) (3) where x s = maximum saturation humidity ratio of air (kg water kg air, lb water lb dry_air) p ws = saturation pressure of water vapor

- Psychrometric Calculator
Calculate online thermodynamic properties of moist (humid) air based on Hyland and Wexler formulation approved by American Society of Heating, Refrigeration and Air-conditioning Engineers 2 Relative humidity [RH]: % 3 Pressure (absolute) [P]: bar : Calculate Saturation pressure at wet bulb temperature Pwb : bar psi Pressure: p = 1
- READY Tools - Moisture Calculator
Enter the air temperature (C) and wet bulb or dew point temperature or RH All other values, except wet bulb, will be recalculated when you click or tab away from the entry box Click on the "Lock DP" box to enter a new temperature at the same dew point This allows calculation of the RH that the air will acquire at a different temperature
- Mixing Ratio of Air Calculator
The actual mixing ratio is a more sensitive way of differentiating various air streams than the relative humidity For instance, a hot kitchen and a cold Alaskan street may have similar humidity but different mixing ratios Atmospheric thermodynamics to find the value of the virtual temperature of a parcel of air This is the temperature dry
