A dirty filter can add 0.20-$0.40 in. w.c. quickly.

(Where C8 is CFM, D8 is Width, and E8 is Height. The 144 converts square inches to square feet) 3. Fitting Loss Calculation (The -Factor Method) esp calculation hvac excel sheet

This tab tracks the (the longest path of highest resistance from the fan to the farthest terminal device). Structure your columns from left to right as follows: Segment ID (Col A): e.g., S-1, S-2, S-3.

Fitting Pressure Drop=VP×CoFitting Pressure Drop equals VP cross cap C sub o Convert this into a single automated cell formula: = ((G8 / 4005)^2) * I8 Use code with caution.

Use load calculations (Manual J) to determine the required airflow. 2. Measure or Estimate Duct Resistance

Identify the longest, most restrictive run of ductwork from the fan to the farthest grille. Your Excel rows will represent the sequential parts of this specific path. 3. Column Layout Blueprint

The ESP calculation typically involves the following steps:
