About this exam
The NCEES PE Mechanical: Thermal and Fluid Systems Exam is a discipline-specific Principles and Practice of Engineering exam for mechanical engineers pursuing professional licensure in the United States. It assesses whether candidates can apply engineering knowledge and judgment to thermal and fluid systems, rather than simply recall formulas. The exam is intended for engineers with relevant education and experience. Passing it is one part of the licensure process; state and territorial boards set their own eligibility, experience, and application requirements, so check your board’s rules before registering.
The computer-based exam covers applied mechanical engineering topics such as thermodynamics, heat transfer, fluid mechanics, and thermal or power systems. Review thermodynamic properties, first-law energy balances, entropy and second-law analysis, Rankine cycles, gas power cycles, turbines, and engine performance. Candidates use the NCEES-provided reference handbook, so preparation should include finding equations and tables efficiently as well as solving problems. Exam specifications and logistics can change, so use the current NCEES materials for the applicable exam cycle.
How to prepare for the PE Mechanical: Thermal and Fluid Systems exam
- Download the current NCEES PE Mechanical: Thermal and Fluid Systems exam specifications and use them to build a topic checklist, giving extra review time to areas where you have less recent work experience.
- Practice setting up thermodynamic and energy-balance problems from the given data, stating assumptions, tracking units, and checking whether your result is physically reasonable.
- Complete timed mixed-topic problem sets using the NCEES reference handbook, then review each error to identify whether it came from concepts, calculations, or locating a reference.
FAQ
Who is eligible to take the PE Mechanical: Thermal and Fluid Systems exam?
Eligibility is set by the state or territorial licensing board where you plan to apply. Requirements commonly involve an engineering education, the FE exam, and qualifying experience, but rules and the timing of exam approval vary. Check with your board and NCEES before registering.
What is the format of the PE Mechanical: Thermal and Fluid Systems exam?
NCEES currently lists the exam as computer-based with 80 questions and an 8-hour exam session within a 9-hour appointment. Confirm the current exam specifications for the cycle you plan to take, including question formats and testing procedures.
What subjects should I study for the Thermal and Fluid Systems PE exam?
Review the current NCEES exam specifications, with attention to thermodynamics, heat transfer, fluid mechanics, and thermal or power systems. Topics include energy balances, entropy, Rankine and gas power cycles, turbines, and engine performance. Practice applying concepts to unfamiliar problems, not just memorizing equations.
