PE Mechanical Thermal Fluids study plan

PE Mechanical Thermal Fluids · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Thermal and Fluid Systems

  • Inventory the full exam topic list for Thermal and Fluid Systems and map each topic to a confidence rating (high, medium, low) so the remaining seven weeks target only weak areas.

  • Derive and memorize the core fluid statics relations - hydrostatic pressure variation, manometry, forces on submerged plane and curved surfaces, and buoyancy - and solve at least 15 practice problems without notes.

  • Re-derive the continuity and Bernoulli equations from a control-volume energy balance, then apply them to pipe flow, nozzles, and Pitot-static problems.

  • Build a one-page formula sheet for fluid statics and ideal-flow energy equations, organized by problem type rather than by textbook chapter.

Your checkpoint

A graded self-assessment table listing every exam topic with a confidence score and a prioritized weak-topic list of no more than 12 items.

Week 2

Thermal and Fluid Systems

  • Compute Reynolds number, friction factor (Moody chart and Colebrook correlation), and major/minor head losses for series and parallel pipe networks.

  • Apply the Darcy-Weisbach and Hazen-Williams approaches and explain when each is appropriate.

  • Solve pump-system curve intersection problems, including NPSH available versus required and cavitation screening.

  • Practice dimensional analysis and similitude problems, deriving dimensionless groups and scaling model data to prototype conditions.

Your checkpoint

A worked solutions packet of 20 pipe-flow and pump problems, each with a labeled sketch, unit-checked answer, and a note on the most common trap.

Week 3

Thermal and Fluid Systems

  • Set up and solve steady conduction problems in plane walls, cylinders, and spheres, including composite resistances and contact resistance.

  • Apply the lumped-capacitance model and the Biot number criterion, and solve transient conduction using charts or one-term approximations.

  • Compute convection coefficients using the standard Nusselt correlations for internal and external flow, selecting the correct characteristic length each time.

  • Analyze fin performance using efficiency and effectiveness, and decide when fins are worthwhile.

Your checkpoint

A heat-transfer resistance-network portfolio of 15 solved problems spanning conduction, convection, and fins, with all characteristic lengths and properties explicitly justified.

Week 4

Thermal and Fluid Systems

  • Solve radiation heat exchange problems using view factors, the Stefan-Boltzmann law, and gray-surface networks for two- and three-surface enclosures.

  • Analyze heat exchangers using both LMTD and effectiveness-NTU methods, including correction factors for multipass configurations.

  • Rehearse the full exam topic list under timed conditions to identify remaining gaps before the second half of the plan.

  • Review every missed item from weeks 1 through 4 and rewrite the formula sheet to close those gaps.

Your checkpoint

A timed 40-question mixed practice set on fluid mechanics and heat transfer, scored, with every wrong answer corrected and annotated with the underlying concept.

Week 5

Thermal and Fluid Systems

  • Apply the first and second laws of thermodynamics to open and closed systems, including steady-flow devices such as turbines, compressors, and nozzles.

  • Analyze ideal and real gas power cycles - Rankine, Brayton, Otto, and Diesel - computing thermal efficiency and identifying irreversibility.

  • Solve refrigeration and heat pump cycle problems, including coefficient of performance and cascade or multistage arrangements.

  • Compute entropy changes and apply the isentropic relations for ideal gases with variable specific heats.

Your checkpoint

A cycle-analysis summary sheet comparing four power cycles and two refrigeration cycles, with governing equations, efficiency expressions, and one fully worked numeric example each.

Week 6

Thermal and Fluid Systems

  • Analyze psychrometric processes - sensible and latent heating, cooling and dehumidification, humidification, and mixing - using the psychrometric chart and humidity-ratio relations.

  • Solve combustion problems including stoichiometric air-fuel ratio, excess air, and adiabatic flame temperature.

  • Apply the three modes of heat transfer together in combined-mode problems such as insulated pipes and heat-exchanger surfaces.

  • Practice HVAC load estimation and air-distribution calculations tied to psychrometric state points.

Your checkpoint

A psychrometrics and combustion problem set of 15 items with plotted or tabulated state points and a worked adiabatic flame temperature calculation.

Week 7

Thermal and Fluid Systems

  • Solve turbomachinery problems involving pump and fan affinity laws, specific speed, and impeller scaling.

  • Analyze compressible flow through nozzles and ducts, including choked flow, Mach number relations, and normal shocks.

  • Work through instrumentation and measurement items - orifice and venturi meters, thermocouples, and uncertainty propagation.

  • Complete a second timed practice exam and log every error by root cause: concept gap, unit slip, misread, or time pressure.

Your checkpoint

A timed 40-question practice exam with a root-cause error log and a targeted remediation list for week 8.

Week 8

Thermal and Fluid Systems

  • Re-solve every item in the root-cause error log until each is correct without reference material.

  • Drill the formula sheet from memory, reconstructing it from blank paper twice under time pressure.

  • Take one final full-length timed practice exam under realistic conditions and review it the same day.

  • Confirm exam-day logistics - reference handbook familiarity, calculator policy, and a pacing plan for the question count.

Your checkpoint

A clean, final one-page reference sheet reconstructed from memory plus a scored final practice exam showing improvement over the week 7 attempt.

Milestones

Week 2: Score at least 70 percent on a self-made 20-question fluid mechanics quiz covering statics, pipe flow, and pumps, with all unit conversions correct.

Week 4: Complete the timed 40-question mixed set at or above 65 percent and reduce the weak-topic list to 10 items or fewer.

Week 6: Solve a combined psychrometrics and combustion problem end to end without consulting notes, and explain each step aloud.

Week 8: Score at or above 75 percent on the final full-length timed exam and reconstruct the reference sheet from memory with no missing governing equation.
