A Systems Approach To Pressure Screen Control In The Pulp Mill

Papermaking Approach Flow Text

Papermaking Approach Flow Text

Approach Flow Page 5 account for this, the shape of the manifold must assume a complex exponential shape, as shown in Figure 7. Another pressure loss occurs from boundary layer separation at the entries to the tube bank, giving a "loss coefficient". This requires the manifold shape to be even more complex to maintain constant pressure.
