Tearing several bags apart, he saw the problem — the bags' pores, which separate the dirt from the air passing through the bag, quickly became blocked with dust, constricting the airflow and reducing the suction.
If the retina is inadvertently sucked into the cutter, the surgeon must react quickly to release the pedal, thereby stopping or reducing the suction force.
Our results indicating a lack of divergence in mouth size make sense in the context of benthic suction feeding, as a larger mouth would increase the area of the fish's buccal cavity, reducing the suction pressure it could exert on attached prey.
The modification of the edge is very effective to reduce the peak suction, as it controls effectively the separation of the shear layer.
Different methods to reduce the high suction caused by conical vortices have been reported in the literature: vertical parapets, either solid or porous, placed at the roof edges being the most analysed configuration.
Low-height parapets with a medium porosity and cantilevered parapets are more efficient than solid parapets to reduce the wind suctions generated on the roofs by conical vortices.
During renovations, West Caldwell added a secondary pool drain to reduce the amount of suction at each drain, making it less likely someone could get trapped, said Gordon Bruchac, the town recreation director.
Spanwise flow effects are shown to reduce the strength of the suction peak on the outboard blade sections, reducing the likelihood of cavitation inception.
Reducing the negative suction pressure applied to the drain (making it half suction) along with external compression dressings applied for first 48 hours can significantly reduce drainage from the axilla following modified radical mastectomy without increasing the incidence of seroma formation as was observed in this randomized prospective clinical study.
Their initiation in unsaturated soils is regulated by rainfall infiltration which reduces the matric suction and hence shear strength.
