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 H_{2}O
37.043

Pressure in PSI
1.3382
