Fluid is defined as any gas or liquid that adapts shape of its container. When the fluid goes bad, problems surface. Momentum thickness is defined as the distance by which the boundary should be displaced to compensate for the reduction in momentum of the flowing fluid on account of boundary layer formation. The Mechanics of Metalworking Fluids We usually don't think of coolant maintenance as mechanical, but this is the most important aspect, which keeps the the chemistry and biology in proper order. One of the prerequisites is Dynamics. the forces acting on an element of fluid to its acceleration or rate of change of momentum.
