stage is from the exit side of support blade 4 to the edge of the step 15 step a is sized according to the amount of water coming from previous elements and the water drained at this stage in the first stage water is reintroduce to the fiber slurry 1 and high shear effect is developed from the beginning of the second stage up to the maximum point of wire deflection high activity is developed due to the eddy currents at the step and the instantaneous differential velocities between the water 7 and the forming fabric 13 side a is the higher pressure side of the blade and thus water will always flow in direction towards side b of the blade ultimately resulting in drainage fig2 provides a model for determining the dynamic pressure developed on the forming fabric which can be calculated by the following equation where u2018 m u2019 is deflection of the wire in inches u2018 c u2019 is the span of the wire in inches u2018 vm u2019 is the machine speed in feet per minute and u2018 k u2019 is a constant of value 0 82864451984491991898e 3 the dynamic pressure developed on the forming fabric is proportional to the gravitational or centrifugal force experienced by the forming fabric which is commonly referred to as the u2018 g force u2019 and usually lies in the range of 1 to 10 however values between 3 and 5 are preferable those of skill in the art will recognize that other values for u2018 k u2019 can be used to undertake this.
