The nozzle spacing is computed by the following:
=
( ll² + lc² ) where
ll - Arc length along the inside vessel surface in the long. direction.
lc - Arc length along the inside vessel surface in the circ. direction
If any interferences/violations are found, they will be noted below.
No interference violations have been detected!

General Notes for the above table:
The cut length is the outside projection + inside projection + drop + in-plane shell
thickness. This value does not include weld gaps, nor does it account for shrinkage.
In the case of oblique nozzles, the outside diameter must be increased. The re-pad width
around the nozzle is calculated as follows:
Width of Pad = (Pad Outside Dia. (per above) - Nozzle Outside Dia.)/2
For hub nozzles, the thickness and diameter shown are those of the smaller and thinner section.

There were no geometry errors or warnings.
PV Elite performs all calculations internally in Imperial Units
to remain compliant with the ASME Code and any built in assumptions
in the ASME Code formulas. The finalized results are reflected to show
the set of selected units for this analysis.
Information Regarding Nozzle Loads
Please note that nozzle loadings, if included, are assumed to be local in nature
and will not contribute to or create a net section bending moment. Therefore, the
addition of nozzle loads will not affect the support load calculation. If you wish
to create a load on the support(s) from nozzle loads, you can enable that feature in
tools->configuration->Job Specific Settings.
One or more nozzles in this model was specified using the actual thickness basis and a standard
flange is also specified. In many cases a matching nominal diameter cannot be determined and
the weight of the flange and optional blind flange cannot be determined. When actual thickness
basis is specified, you must calculate the weight of the assembly (by hand) and enter it into
the 'Overriding Weight' field in the nozzle dialog when there is a standard flange
specified. However, for FVC nozzles that have their nominal diameter specified in the
FVC dialog, entering the overriding weight for that nozzle is not required.
The level of precision is set to a value of less than 3. At this level you may not
obtain proper resolution on some results. This value can be changed in
Tools->Set Configuration Parameters->Default Values->Level of Precision.

PV Elite includes an 1/8 inch (3.175mm) raised face and gasket thicknesses for girth
flanges and tubesheet thicknesses where applicable in the Tangent to Tangent length calculation.
The calculated dimensions are based on the given element lengths. Due to variability in
manufacturing (weld gaps etc.), the Tangent to Tangent length may not be exact.

Selected Method for Derating ASME B16.5 Flange MAWP: ASME UG-44(b)
The UG-44(b) Method is based on the paper PVP 2013-97814. PV Elite uses the maximum loads
from each load category to determine ME and FE. In many cases, the computed maximum
allowable pressure will be greater than the flange rating. In these cases, the minimum of the
rating from the table and the UG-44(b) method will be used. SA-193 B8 Cl. 2 bolts or ones
with higher allowable stresses at the specified bolt size shall be used.
The axial force FE must put the nozzle in tension (-P for 107/297; +Fr for PD 5500 AnnexG)
to be considered.

The importance factor is not used in the calculation of wind pressure vs. elevation for
the selected wind code.
Static Gust-Effect Factor, Operating Case [G]:

This is classified as a rigid structure. Static analysis performed.
Sample Calculation for the First Element:
The ASCE code performs calculations in Imperial Units. The wind pressure is therefore computed
in these units.
Value of [α] and [Zg]:
Exposure Category: C from Table 26.9.1
α = 9.5: Zg = 274320.0 mm
Effective Height [z]:
= Centroid Height + Vessel Base Elevation
= 2350.0 + 0.0 = 2350.0 mm
= 7.71 ft. Imperial Units
Velocity Pressure coefficient evaluated at height z [Kz]:

Because z (7.71 ft.) < 15 ft.
= 2.01( 15 / Zg )2/α
= 2.01( 15/900.0 )2/9.5
= 0.849
Type of Hill: No Hill
Wind Directionality Factor [Kd]:
= 0.95, per Table 26.6-1
As there is No Hill Present: [Kzt]:
K1 = 0, K2 = 0, K3 = 0
Topographical Factor [Kzt]:
= ( 1 + K1 • K2 • K3 )²
= ( 1 + 0.0• 0.0• 0.0 )²
= 1.0
Velocity Pressure evaluated at height z, Imperial Units [qz]:
= max( 16, 0.00256 • Kz • Kzt • Kd • V(mph)² )
= max( 16, 0.00256 • 0.849 • 1.0 • 0.95 • 111.85² )
= 25.8 psf [1.237] kPa
Force on the first element [F]:

WRC 107/537 has dimensional limitations that can be found in the bulletin's Foreword
and which can also be inferred by review of the non-dimensional curve limits.
