phenomena controlled by flow of water between fibres and from the fibre wall. The structural resistance from the fibres themselves is normally a minor portion at today's dryness levels of between 30% and 50%. The distinction between pressure controlled and flow controlled pressing is very important in understanding pressing (Wahlstrom, 1976).

Milling (machining) - Wikipedia
Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece.This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations.
Improving Fan System Performance
fan airflow-pressure curve. Oversized fans generate excess flow energy, resulting in high airflow noise and increased stress on the fan and the system. Consequently, oversized fans not only cost more to purchase and to operate, they create avoidable system performance problems. The use of a "systems approach" in the fan selection process
