In the desiccant dehumidification formula, what is done to calculate Total CFM Recommendation?

Cubic Footage ÷ 60 x Chart Factor
Cubic Footage x 60 ÷ Chart Factor
Cubic Footage x Chart Factor ÷ 60
Cubic Footage ÷ Chart Factor x 60

The correct answer is: Cubic Footage ÷ 60 x Chart Factor

To calculate the Total CFM Recommendation in the desiccant dehumidification formula, dividing the cubic footage by 60 and then multiplying by the chart factor is the correct approach. This formula helps in determining the appropriate air flow rate required for effective moisture removal based on the size of the space and the efficiency of the specific dehumidification system being used. When the cubic footage of the area is divided by 60, it converts the volume into a per-minute basis, allowing for a standardized measure for air flow (CFM stands for Cubic Feet per Minute). Following this step, multiplying by the chart factor accounts for the specific conditions and definitions applied within the chart or guidelines, which might consider factors such as the desired humidity level, the nature of the water damage, and the specific characteristics of the dehumidifier. Using this method ensures that the total air flow is tailored to effectively manage the moisture levels in the space, leading to successful water restoration.
