10O. Equivalent Length Calculations using Equations in Table 10.2 Back to
Main
This
page is used to determine the equivalent length of a pipeline transporting
liquids with multiple pipe segments (up to 4 pipe segments). The situation often arises when it is
convenient to use several diameters of pipe in series. Fluid principles also may be applied in this
case after proper analysis of the conditions present. However, no single equation can be written between the varying
diameters. A convenient solution is
afforded by determining a single-diameter line that is equivalent to the
multiple segments. If the physical
properties of the fluid remain essentially unchanged throughout the line the
following equation can be used.
