&lt;p&gt;Answer:&lt;/p&gt;
&lt;p style="padding-left:60px;"&gt;Given the vessel is 6040mm dia with a wall thickness&amp;nbsp; = 20mm and Limpet / Half pipe coli with a pitch of 150 mm and 40 mm radius.&lt;/p&gt;
&lt;p style="padding-left:60px;"&gt;Referencing,&amp;nbsp;ASME VIII Div 1, appendix EE, figure EE-2 (DN80), the K factor would be read, but parameter D is beyond the scope of the limits of the chart (D = 6040 mm / 25.4 mm = 237.79 in).&lt;/p&gt;
&lt;p style="padding-left:60px;"&gt;&lt;img alt=" " src="/resized-image/__size/320x240/__key/communityserver-wikis-components-files/00-00-00-00-41/38222.png" /&gt;&lt;/p&gt;
&lt;p style="padding-left:60px;"&gt;Other applications like PV Elite considers the Diameter D = 170 instead of 237.79, then they have a K value found from reading the chart. However, as mentioned, the actual geometry is beyond the chart.&lt;/p&gt;
&lt;p style="padding-left:90px;"&gt;How to best find the correct value of K ?&lt;/p&gt;
&lt;p style="padding-left:60px;"&gt;Upon further investigation of:&lt;/p&gt;
&lt;p style="padding-left:90px;"&gt;&lt;span&gt;a. b. ASME VIII div.1 NONMANDATORY APPENDIX EE HALF-PIPE JACKETS,&lt;/span&gt;&lt;/p&gt;
&lt;p style="padding-left:90px;"&gt;&lt;span&gt;b. ASME VIII div.2 4.11.5 DESIGN OF PARTIAL JACKETS&lt;/span&gt;&lt;/p&gt;
&lt;p style="padding-left:60px;"&gt;Find that&amp;nbsp;ASME VIII div.2 4.11.5 uses equations instead of charts to determine the K factor.&amp;nbsp;&lt;/p&gt;
&lt;div style="padding-left:60px;"&gt;Therefore, the K factor obtain in&amp;nbsp;AutoPIPE Vessel come from equations which are matching charts in the scope of ASME VIII div.1. In addition, there is no limitation explained in ASME VIII 2 about the scope of this application.&lt;/div&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;
