The friction pressure loss is modified in several ways, by adjusting the friction factor (f), the density (ρ) and velocity (v) to account for multiphase mixture properties. The multiphase pressure loss correlations in F.A.S.T. Harmony TM are based on the Fanning friction pressure loss equation.

Total dynamic head is the major factor that determines the optimal performances of submersible pumps. If the total head on the system increased, the volume of the discharge will be reduced proportionally until its stops.
The friction factor is maybe the most uncertain factor in the calculations. This is because the friction factor is not a measured parameter but it is a fudge factor. This fudge factor depends on other effects including mud system lubricity, pipe stiffness, cuttings beds, hydraulic piston effects and tortuosity [18] .

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
Vertical mills appeared in subsequent decades, and accessories in the form of add-on heads to change horizontal mills to vertical mills (and later vice versa) have been commonly used. Even in the CNC era, a heavy workpiece needing machining on multiple sides lends itself to a horizontal machining center, while diesinking lends itself to a ...
Selected design factors are friction factor, reductions in each stand, back tension of first stand (equals with front tension of last stand ), inter-stand tensions and speed of the strip. The value of the rolling process parameters in any level are listed in Table 1 .
