  • What is Bernoulli s EquationBernoulli s Principle

     · In general pressure is a measure of the force exerted per unit area on the boundaries of a substance.The term dynamic pressure (sometimes called velocity pressure) is associated with fluid flow and with the Bernoulli s effect which is described by the Bernoulli s equation . This effect causes the lowering of fluid pressure (static pressure) in regions where the flow velocity is increased.

A joint of this kind is called a friction joint. If the clamping force is not sufficient to create the friction needed the screw will also be exposed to the shear load.

     · Yttria-reinforced copper matrix composites were prepared by dry ball milling (DBM) and wet ball milling (WBM) respectively followed by spark plasma sintering (SPS). It is to determine which milling process is better for fabricating Cu–Y2O3 composites. It is found that Cu–Y2O3 composites synthesized by DBM exhibit better densification mechanical and electrical properties than those by WBM.

  • Ball Millan overview ScienceDirect Topics

    Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.- ore and 25 steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
