I=
= ( (Ihigh - Ilow) * (C - Clow) / (Chigh - Clow) ) + Ilow
is used, where:
I = the (Air Quality) index,
C = the pollutant concentration,
Clow= the concentration breakpoint that is ≤ C,
Chigh= the concentration breakpoint that is ≥ C,
Ilow= the index breakpoint corresponding to Clow,
Ihigh= the index breakpoint corresponding to Chigh.
AQI stands for air quality index which is used in places to see if air quality is breathable
COOLING COIL CONDENSATE CAN BE CALCULATED BY THE FOLLOWING FORMULA" CC CONDENSATE (GPM)=(4.5/500)*CFM*CHANGE IN HUMIDITY RATIO OF THE AIR(LB/MOISTER/LB OF DRY AIR)
To calculate the volume of air in a room, measure the room's length, width, and height in the same units (e.g., meters or feet). Then, use the formula for volume: Volume = Length × Width × Height. For example, if a room is 5 meters long, 4 meters wide, and 3 meters high, the volume of air would be 5 × 4 × 3 = 60 cubic meters. This volume represents the total space available for air within the room.
To calculate BTUs from CFM (Cubic Feet per Minute) and wet bulb temperatures, you can use the formula: BTUs = CFM × 4.5 × (Wb1 - Wb2), where Wb1 is the wet bulb temperature entering the system and Wb2 is the wet bulb temperature exiting the system. This formula accounts for the energy required to change the moisture content of the air. Be sure to convert temperatures to the same unit (usually Fahrenheit) before applying the formula.

Air Quality Health Index was created in 2005.
The Air Quality Index (AQI) also known as the Air Pollution Index (API) or Pollutant Standard Index (PSI)), is an indicator of air quality, based on pollutants that have adverse effects on human health and the environment.

Air Quality Index
Air quality in the UK is measured using a network of monitoring stations that measure various pollutants such as particulate matter, nitrogen dioxide, and ozone. The data collected from these stations is then used to calculate air quality indices which provide information on the level of pollution in the air and its potential effects on health. This information is made publicly available to raise awareness and inform actions to improve air quality.
An air quality index of 0-15 is considered good, with little to no risk to health. This level indicates that the air quality is clean and poses minimal health concerns for the general population.

During the 1970s, the air quality index in Los Angeles was often very poor due to high levels of pollution from vehicles and industry.
