The prompt
You are tasked with designing a 2D pressure vessel in AutoCAD for storing liquid hydrogen. Consider the following: a) b) c) Hydrogen has a very low boiling point (20 K or –253°C), low density ( 70.85 kg/m³), high flammability, and high diffusivity. The vessel will operate at high pressure (~4 bar) and cryogenic temperatures (~20 K). The vessel includes a cylindrical shell, hemispherical or ellipsoidal heads, nozzles, flanges, and support structures.
