10G. Parallel (Loop) lines by Weymouth and Panhandle A Back to Main

This page is used to determine Parallel (loop) lines by two different methods; the Weymouth and the Panhandle A method. The principles outlined for liquid flow also apply to steady-state gas flow. The equations used for these calculations are listed in Table 10.4 in the book Gas Conditioning and Processing Volume 1.

To calculate the parallel (loop) lines, the method of calculation must be decided. Choose Weymouth or Panhandle A by clicking on and shading the circle provided for that selection. Once a method of calculation has been made the Percent increase in flow rate, Existing pipe diameter, and Looped line diameter must be entered into their entry space. To do so use the mouse to click the curser in the entry spaces and input the data. Once this has been done, select Run to execute the solution.

The Percent increase in flow rate is the amount it is desired to increase the capacity of an existing pipeline system.

The Existing pipe diameter is the inside diameter of the original line, on the current existing system, before looping.

The Looped line diameter is the inside diameter of the section of line added to the system.
