Orientation Calculation

This document provides calculations for arc lengths and angles of radial and tangential nozzles on vessel shells and dishes. It includes the vessel ID, thickness, nozzle projection distances, and angles needed to calculate the arc lengths. Standard nozzle sizes from NPS 0.5 to 24 are also listed with their diameters in millimeters.
