where
£ = Radius
L = Length of flow channel

for — > 20
H
where H is the height of the slit and W is the width.
W
For — < 20, Gslit has to be multiplied by the correction factor Fp given in Figure 5.1
H
The factor F can be expressed as
The die constant G3J1n^118 is calculated from

where R0 is the outer radius and JR1 is the inner radius. Gannulus then follows from
