&lt;p style="margin-left:30px;"&gt;&lt;strong&gt;&lt;span style="background-color:#008000;color:#ffffff;font-size:150%;"&gt;Answer:&amp;nbsp;&lt;/span&gt;&lt;/strong&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span style="color:#008000;"&gt;The setting for the nozzle joint efficiency for eg. nozzle &amp;#39;D&amp;#39; in question is as follows in the nozzle dialog box:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&amp;nbsp;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-41/2146.2.png"&gt;&lt;span style="color:#008000;"&gt;&lt;img alt=" " src="/resized-image/__size/720x0/__key/communityserver-wikis-components-files/00-00-00-00-41/2146.2.png" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span style="color:#008000;"&gt;As shown above the joint efficiency has been set as 0.9.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span style="color:#008000;"&gt;In the report it is 1.0:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-41/6443.3.png"&gt;&lt;span style="color:#008000;"&gt;&lt;img alt=" " src="/resized-image/__size/720x0/__key/communityserver-wikis-components-files/00-00-00-00-41/6443.3.png" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span style="color:#008000;"&gt;This is because ASME and GOST have different rules with respect to nozzle joint efficiency. See the paragraph from GOST below:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-41/8103.1.png"&gt;&lt;span style="color:#008000;"&gt;&lt;img alt=" " src="/resized-image/__size/720x0/__key/communityserver-wikis-components-files/00-00-00-00-41/8103.1.png" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span style="color:#008000;"&gt;Hence following the rule above:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span style="color:#008000;"&gt;1. The value of phi = 1, since the distance of the nozzle outer from the right tangent line (X) is more than 3s&amp;nbsp; for nozzle D:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-41/7343.4.png"&gt;&lt;span style="color:#008000;"&gt;&lt;img alt=" " src="/resized-image/__size/720x0/__key/communityserver-wikis-components-files/00-00-00-00-41/7343.4.png" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span style="color:#008000;"&gt;2. For the value of phi1, following the rule above (refer to the sketch in the GOST paragraph above), the long seam weld of the nozzle neck made from plate is assumed to be beyond 60 deg from the longitudinal seam weld of the shell. This is programmed into the software assuming good practice and user unfortunately cannot change this value hence phi1 is always 1.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span style="color:#008000;"&gt;If for example the nozzle D is shifted very close to the right tangent line and a self reinforced nozzle is used such that the outer surface of the nozzle is less than 3s distance from the right tangent line, the value of phi in the report is considered 0.9.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-41/0537.5.png"&gt;&lt;span style="color:#008000;"&gt;&lt;img alt=" " src="/resized-image/__size/720x0/__key/communityserver-wikis-components-files/00-00-00-00-41/0537.5.png" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;

&lt;p&gt;&lt;/p&gt;
&lt;p&gt;As shown above the joint efficiency has been set as 0.9.&lt;/p&gt;
&lt;p&gt;In the report it is 1.0:&lt;/p&gt;
&lt;p&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-41/6443.3.png"&gt;&lt;img alt=" " src="/resized-image/__size/720x0/__key/communityserver-wikis-components-files/00-00-00-00-41/6443.3.png" /&gt;&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Hence following the rule above:&lt;/p&gt;
&lt;p&gt;1. The value of phi = 1, since the distance of the nozzle outer from the right tangent line (X) is more than 3s&amp;nbsp; for nozzle D:&lt;/p&gt;

&lt;p&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-41/7343.4.png"&gt;&lt;img alt=" " src="/resized-image/__size/720x0/__key/communityserver-wikis-components-files/00-00-00-00-41/7343.4.png" /&gt;&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;2. For the value of phi1, following the rule above (refer to the sketch in the GOST paragraph above), the long seam weld of the nozzle neck made from plate is assumed to be beyond 60 deg from the longitudinal seam weld of the shell. This is programmed into the software assuming good practice and user unfortunately cannot change this value hence phi1 is always 1.&lt;/p&gt;
&lt;p&gt;If for example the nozzle D is shifted very close to the right tangent line and a self reinforced nozzle is used such that the outer surface of the nozzle is less than 3s distance from the right tangent line, the value of phi in the report is considered 0.9.&lt;/p&gt;

&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;

&lt;p&gt;Ans:&amp;nbsp;The setting for the nozzle joint efficiency for eg. nozzle &amp;#39;D&amp;#39; in question is as follows in the nozzle dialog box:&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-41/2146.2.png"&gt;&lt;img alt=" " src="/resized-image/__size/720x0/__key/communityserver-wikis-components-files/00-00-00-00-41/2146.2.png" /&gt;&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;As shown above the joint efficiency has been set as 0.9.&lt;/p&gt;
&lt;p&gt;In the report it is 1.0:&lt;/p&gt;
&lt;p&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-41/6443.3.png"&gt;&lt;img alt=" " src="/resized-image/__size/720x0/__key/communityserver-wikis-components-files/00-00-00-00-41/6443.3.png" /&gt;&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;This is because ASME and GOST have different rules with respect to nozzle joint efficiency. See the paragraph from GOST below:&lt;/p&gt;
&lt;p&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-41/8103.1.png"&gt;&lt;img alt=" " src="/resized-image/__size/720x0/__key/communityserver-wikis-components-files/00-00-00-00-41/8103.1.png" /&gt;&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Hence following the rule above:&lt;/p&gt;
&lt;p&gt;1. The value of phi = 1, since the distance of the nozzle outer from the right tangent line (X) is more than 3s&amp;nbsp; for nozzle D:&lt;/p&gt;
&lt;p&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-41/7343.4.png"&gt;&lt;img src="/resized-image/__size/720x0/__key/communityserver-wikis-components-files/00-00-00-00-41/7343.4.png" alt=" " /&gt;&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;2. For the value of phi1, following the rule above (refer to the sketch in the GOST paragraph above), the long seam weld of the nozzle neck made from plate is assumed to be beyond 60 deg from the longitudinal seam weld of the shell. This is programmed into the software assuming good practice and user unfortunately cannot change this value hence phi1 is always 1.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;

&lt;p&gt;&amp;nbsp;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-41/2146.2.png"&gt;&lt;img src="/resized-image/__size/720x0/__key/communityserver-wikis-components-files/00-00-00-00-41/2146.2.png" alt=" " /&gt;&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;As shown above the joint efficiency has been set as 0.9.&lt;/p&gt;
&lt;p&gt;In the report it is 1.0:&lt;/p&gt;
&lt;p&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-41/6443.3.png"&gt;&lt;img src="/resized-image/__size/720x0/__key/communityserver-wikis-components-files/00-00-00-00-41/6443.3.png" alt=" " /&gt;&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;This is because ASME and GOST have different rules with respect to nozzle joint efficiency. See the paragraph from GOST below:&lt;/p&gt;
&lt;p&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-41/8103.1.png"&gt;&lt;img src="/resized-image/__size/720x0/__key/communityserver-wikis-components-files/00-00-00-00-41/8103.1.png" alt=" " /&gt;&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Hence following the rule above the value has been set as 1. in the report even though it is stated by the user&amp;nbsp;as 0.9 in the nozzle&amp;nbsp;dialog box.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;
