The milling process – definitions Cutting speed,v c Indicates the surface speed at which the cutting edge machines the workpiece. Effective or true cutting speed, v e Indicates the surface speed at the effective diameter (DC ap).This value is necessary for determining the true cutting data at the actual depth of cut (a p).This is a particularly important value when using round insert cuttersОнлайн-запрос

To calculate the pressure loss in a pipe it is necessary to compute a pressure drop, usually in fluid head, for each of the items that cause a change in pressure. However to calculate the friction loss in a pipe for example, it is necessary to calculate the friction factor to use in the Darcy-Weisbach equation which determines the overall friction loss.Онлайн-запрос

Under conditions of no seepage flow, the water table will be horizontal, as in the surface of a lake. The magnitude of the pore pressure at the water table is zero. Below the water table, pore pressures are positive. u = g w.h w In conditions of steady-state or variable seepage flow, the calculation of pore pressures becomes more complex.Онлайн-запрос

Absolute pressure can be zero, but it cannot be negative (by definition). Suppose the liquid source was below the pump instead of above?

the negative pressure inside the milling system prevents any material from leaking out. To prevent a toxic material release into the environment during a dust explosion event, you may need to use a chemical suppression system to contain a dust explosion inside the dust collection system, rather than a less-expensive explosion panel that vents pressure and flames outside the building.
