and the pressure to achieve design airflows in the absence of stack pressure is 0.22, derived from 0.10 at each grille and 0.12 to account for duct loss: RPM 2 = RPM 1 SP 2 = 1000 1.91 = 2950 rpm SP 1 0.22 The result is an increase of almost three times the original RPM design in order to prevent changes in airflow due to stack pressure effect.

Jun 18, 2017· Structures difference Between 2-plate mold and 3-plate Mold. The main difference in the structure of the molds lies in the location and orientation of the guide pin, and that the three-plate mold has a small tie bar and a nylon lock on parting surface or latch on the side of the mold to control mold opening sequence and stroke.
Because the ribs present only a small surface area to the mold, their lack of draft creates little resistance to ejection and less risk of damage to the mold. The narrow points where the ribs meet the shaft (or other mating part) allow the ribs to deform during press-fit to ensure
