* A velocity of at least 2000 fpm (610 mpm) helps keep lint particles in suspension.   

 

 

** Equivalent means that the rectangular cross sections have the same pressure drop as the round cross-section. 

 

 

*** Field data determines the number of rectangular cross-sections shown for each dryer model.   

 

 

 

3.2. 

Example Layout

—To provide a more comprehensive example, 

Figure 3

 shows both 

rectangular and round duct. However, avoid using rectangular duct if possible, especially for the 

exhaust ductwork. 

 

Figure 3

 shows the pressure drop values taken from 

Table 2

 and used in the example equations in 

Section 3.3

 superimposed on each piece of duct.
