A home in NY with an N-Factor of 15.4 and a Building Airflow Standard (BAS) of 102 Cubic Feet per Minute (CFM) should have what airflow at CFM50?

To determine the airflow at CFM50 using the given N-Factor and Building Airflow Standard (BAS), one can utilize the formula that relates these values in order to calculate the airflow at a specific pressure.

The N-Factor provides a standard way of representing how the airflow in a building changes relative to pressure changes. In this case, a value of 15.4 indicates that for every standard change in pressure, the airflow will increase by this factor. The BAS of 102 CFM represents the airflow rate of the building at normal conditions.

To calculate the airflow at CFM50, the formula used is:

[ \text{Airflow at CFM50} = \text{BAS} \times \text{N-Factor} ]

Substituting the values,

[ \text{Airflow at CFM50} = 102 , \text{CFM} \times 15.4 ]

Calculating this gives:

[ 102 \times 15.4 = 1570 , \text{CFM50} ]

This calculated value corresponds with the choice provided, confirming that a home in New York with the specified conditions should indeed have an airflow of 1570 C
