• ### mv/A/m

Feb 01 2018  I think the factor 2 or sqrt 3 is taken into consideration in the table data it is built in . For instance on Table 4D1B for 2 2.5 mm 2 the mV/A/m is 18. From IEC 60228 Table II the resistance per meter is 7.41 ohm/km. or 7.41 mΩ/m 1 mΩ/m=1 mV/A/m .

• ### Pressure drop in pipe fittings and valves

The L e /D method simply increases the multiplying factor in Equation 1 i.e. ƒL/D by a length of straight pipe i.e. Le which would give rise to a pressure drop equivalent to the losses in the fittings hence the name equivalent length . The multiplying factor therefore becomes ƒ

### Pressure drop calculation for the shell side in shell and

The pressure drop on the shell side is calculated using . 2 0.14 2 1 ss B shell e s fG D N P D µ ρ µ ∆= In this equation f is a Fanning friction factor for flow on the shell side given in Figure 14 44 of reference 1 G s is the mass velocity on the shell side D.

• ### Flow and pressure drop in valves and fittings

The ratio L/D is equivalent length in pipe diameters of straight pipe that will cause the same pressure drop or head loss as the valves or fittings under the same flow conditions. As the resistance coefficient is K is constant the equivalent length L/D will vary inversely with the change in friction factor for different flow conditions.
