Compare counterflow and parallel flow with a checked thermal example, temperature profiles, model limits, multipass considerations, and supplier review questions.

Choose shell-side and tube-side fluid allocation by reviewing pressure, corrosion, fouling, cleaning access, phase behaviour, and leakage consequences.

Specify shell and tube heat exchanger pressure drop with separate limits, defined measurement boundaries, a checked example, troubleshooting, and test criteria.

Compare LMTD and effectiveness–NTU with formulas, a checked example, model limits, hydraulic considerations, and thermal calculation requirements.

Define heat exchanger approach temperature, calculate terminal differences, and assess thermal limits, utility conditions, cost, and performance testing.

Evaluate automatic tube cleaning for heat exchangers with checks for deposit type, tube geometry, cleaning-element recovery, water treatment, and acceptance.

Understand heat exchanger fouling resistance, area basis, coefficient calculations, sizing sensitivity, pressure drop, and supplier comparisons.

Commission a heat exchanger with mechanical checks, reliable instruments, thermal and hydraulic baselines, functional tests, and clear handover.
