A word of caution if you are using this 2007 tab of this spreadsheet.
The pressure credit is being calculated for the entire supply fan cfm.
It should only be calculated for the design airflow through the device.
While these two airflows can be the same, often they are not.

Yes that is correct, the dot means multiplication.
The Excel calculator will come in very handy (credit to 7 Group)

Does the dot in the equation indicate multiplication? So should the
equation read CFMS X 0.0013 + A?
The reason I am confused is that they use X in other places.
Thanks in advance
