Solve five fluid-mechanics problems on duct and pipe friction (Darcy-Weisbach, Moody chart) and pump/fan affinity laws.

Select chiller type (air-cooled vs water-cooled, centrifugal vs screw vs scroll) for three building scenarios and justify each choice on part-load efficiency and condenser water availability.

Lay out a chilled water distribution scheme with primary/secondary pumping, and size the expansion tank and pump heads.

Design a ventilation strategy for a commercial kitchen, a car park, and an office floor, calculating fresh-air rates and exhaust balances for each.

Check a refrigerant quantity and occupied-space concentration limit against safety classification for a direct-expansion system.

Size cold water supply pipes and storage tanks for a mixed-use building using fixture unit loading and demand curves, showing the calculation steps.

Design soil, waste, and vent stacks for a multi-storey building, checking stack capacity, trap arm lengths, and vent sizing.

Lay out a fire sprinkler and standpipe system for a warehouse and an office floor, calculating hazard classification, design density, and pump duty.

Identify the governing Egyptian code requirements and authority approval path for water supply, drainage, and fire protection submissions, and list the documents each authority expects.

Compare local code provisions with widely referenced international standards on one topic (e.g., sprinkler design density) and note where the stricter requirement governs.

Evaluate prime mover options (diesel generator, gas engine, turbine, grid supply) for a facility load profile and calculate fuel consumption and annual operating cost for each.

Compute heat exchanger duty and effectiveness for a shell-and-tube and a plate unit using the log-mean temperature difference and effectiveness-NTU methods.

Analyze a simple gas turbine or Rankine cycle: calculate thermal efficiency, specific work, and the effect of regeneration or reheat.

Size a compressed air system including receiver volume, dryer selection, and distribution pressure drop for a workshop load.

Interpret a pump and system curve intersection and determine the effect of throttling versus variable speed control on power.

Specify the control sequence of operation for an air handling unit and a chilled water plant, writing each sequence in plain narrative with setpoints and fail-safe positions.

Map mechanical equipment to electrical loads: calculate motor full-load current, starting method, protection coordination needs, and generator/ATS interface for chillers and fire pumps.

Define the points list and network architecture (BACnet/IP backbone, field bus, gateways) for a building automation system covering HVAC, plumbing, and fire interfaces.

Explain fire alarm and fire pump interface requirements with HVAC shutdown, damper control, and smoke management, and identify the signals that must be hard-wired.

Review a sample control schematic and mark up three errors in sensor placement, valve failure position, or interlock logic.

Build a personal index of the Egyptian codes and ministerial decrees relevant to mechanical works, recording issuing body, scope, and where each is referenced in a submission.

Outline the approval workflow from design to occupancy for a new building, naming the authorities and the mechanical inspections at each stage.

Perform a hazard identification and risk assessment for a plant room (refrigerant, fuel, electrical, confined space) and assign controls by hierarchy.

Specify refrigerant safety measures, ventilation rates, gas detection, and emergency shutdown for a machine room, and check against the applicable standard.

Draft a waste management and environmental controls plan for a construction site covering dust, noise, and refrigerant recovery.

Prepare a quantity take-off and cost estimate for a mechanical package (HVAC and plumbing) with rates, preliminaries, contingency, and escalation.

Compare lump-sum, remeasured, and design-build contract forms on risk allocation for the consultant, and identify clauses that shift design liability.

Draft a variation and claim assessment for a delayed equipment delivery, showing time impact and cost build-up.

Analyze three ethics scenarios (conflict of interest in specification, pressure to certify non-compliant work, unpaid fee and withholding of documents) and state the correct professional response.

Define the consultant's standard of care, professional indemnity coverage, and record-keeping that supports a defense against a negligence claim.

Sit two full-length timed mock exams under exam conditions and record the score by domain to expose weak areas.

Re-work every missed item from the mocks to root cause (knowledge gap, misread, calculation error) and close each gap with a targeted reference check.

Recite from memory the key design values, code thresholds, and safety limits you are most likely to be tested on, and verify each against source.

Rehearse a 10-minute verbal defense of one design decision in each of HVAC, plumbing/fire, and power systems as if presenting to an approving authority.

Assemble a one-page personal formula and reference sheet for final review.
