This section offers an in-depth exploration of mechanical engineering principles as they apply to the design, analysis, fabrication, and operation of core industrial equipment used extensively in the oil and gas, petrochemical, and process industries. The content is structured into two primary categories:

• Static Equipment, which includes vessels and tanks that must safely contain fluids under various conditions, requiring rigorous structural analysis, material selection, and adherence to stringent codes and standards.

• Rotating Equipment, encompassing machines that impart or extract energy from fluids, where dynamic performance, reliability, and maintenance are paramount.

Each topic area focuses not only on theoretical concepts but also on practical engineering approaches, calculation methodologies, and compliance with industry codes such as ASME, API, and ISO standards. The content bridges fundamental mechanical engineering with applied industry practices, making it highly relevant for engineers involved in design, project execution, maintenance, and technical evaluation.
