System Sizing Calculation

1. Calculate Exit Area   Enter Quantity, Length, and Velocity (You may change the air knife gap)
1. Enter the Quantity of Air Knives 2. Multiply by the Length of Air Knives in Inches Multiplied by Air Knife Gap (Default Gap: 0.045) Divided by 144 Equals Exit Area in Square Feet (Aexit) 3. Multiply by Velocity in 1000 feet per minute
2. Flow Rate
Equals CFM (Cubic Feet per Minute) Required 90
3. Required Amount of Air Pressure
Pressure in H2O
Pressure in PSI
