The Principles and Practice of Engineering (PE) Mechanical: Thermal and Fluid Systems exam is a comprehensive, discipline-specific licensure examination designed for mechanical engineers who specialize in the design, analysis, and operation of systems involving energy conversion, fluid flow, and heat transfer. This exam assesses a candidate's ability to apply fundamental engineering principles to real-world problems in thermodynamics, fluid mechanics, heat transfer, and fluid machinery. It is intended for engineers with at least four years of progressive experience who are seeking professional licensure (PE) to demonstrate competency in protecting public health, safety, and welfare. The exam covers five core domains: Thermodynamics (including power cycles, refrigeration, and property relationships), Fluid Mechanics (including pipe flow, pumps, and compressible flow), Heat Transfer (conduction, convection, radiation, and heat exchangers), Fluid Machinery (turbines, compressors, fans, and pumps), and Supportive Knowledge (including instrumentation, economics, and system optimization). By passing this exam, candidates validate their ability to independently design thermal-fluid systems, perform energy audits, specify equipment, and troubleshoot operational issues. The exam is open-book and consists of 35 multiple-choice questions, emphasizing applied problem-solving over theoretical derivation. Successful candidates gain the legal authority to sign and seal engineering plans, take professional responsibility for projects, and advance their careers in consulting, manufacturing, energy, and government sectors.
