The calculation was completed in the gPROMS software. The results show that the calculation result of formula 7 is the most conservative, while the calculation result of formula 1 is the smallest. Table 5. Pipe diameter design formulas for the gas pipeline. NumberEquationReference(s) 1 D=2.252...
Diameter Calculation This is the internal diameter of a pipe or duct that would be required for a substance moving at the specified speed and volumetric flow rate. Primary Sidebar Measurement Instrument Specifier Select yourmeasurement instrumentrequirements...
For each new calculation a unique conversion scale will be generated for the range of flow speeds and volumetric flow rates for the diameter specified.FormulaThe volumetric flow rate formulae used by this calculator is:Q = v ·π· (ø / 2)²...
So that a higher E factor in the calculation results in a thinner and therefore lighter pipe. This formula can be found in ASME B31.3 (304, Pressure Design of Components; 304.1, Straight Pipe; 304.1.1, General): (2.1)t=PD2(SE+PY) where P is the internal design gauge pressure. D is...

This is again attributed to the calculation methods being unable to properly represent the large reductions in friction due to properly applied lubrication. Combining the measured data from lubricated drives with the analytical approaches for deeper underground layers resulted in estimates of the unit ...
The calculation formula is shown in Equation (3). F = Mo fo(d) × 100%, Mi fi(d) (3) where fo(d) fi(d) are the contents of a specific particle in overflow and feed inlet, respectively. Mo is the solid-phase mass flow rate of the overflow. For the evaluation of hydrocyclone ...
Pipe (elbow) elements have the advantage in calculation efficiency, but they are incapable of demonstrating the pipe wall folding phenomenon in pipe, when local buckling occurs. Soil constraints on pipe can be modeled by discrete nonlinear soil spring elements or the surface-to-surface contact ...
