2. First calculate the total cloth area of your collector by calculating the total filter area of each filter (bag diameter x 3.14 x length ÷ 144 [for number of inches in a square foot] = filter cloth area) and then multiply that figure by the total number of bags in the collector. 3. Take the CFM of the system and divide it by
Efficiency is a measure of how much work or energy is conserved in a process. In many processes, work or energy is lost, for example as waste heat or vibration. The efficiency is the energy output, divided by the energy input, and expressed as a percentage. A perfect process would have an efficiency of 100%.

ΔT°F = 72°F 58°F = 14°F
Once your Carrier ® dealer has completed a load calculation to determine the proper size furnace for your home, you still have decisions to make. That’s because two furnaces with the same heating capacity can have different efficiency ratings. Furnace efficiency ratings are expressed in terms of AFUE percentage and will be displayed on the furnace with the yellow Energy Guide label.
