Engineering reference data for preliminary calculations.
Reference tables with typical values, ranges, assumptions, and context for preliminary engineering calculations. Each reference explains what the values are for, the units used, the assumptions behind them, and how they can support early-stage estimates.
These references complement the interactive calculators and engineering guides by making common input assumptions explicit. They support preliminary estimates — not final design, procurement, compliance, or vendor-rating decisions.

Heat exchanger sizing
Typical values and standards context for preliminary shell-and-tube and plate heat exchanger sizing.
Heat Exchanger Typical U-Values Reference
Typical overall heat transfer coefficient (U-value) ranges for common heat exchanger types and fluid combinations. Use for preliminary sizing estimates — not final design values.
Heat Exchanger Fouling Factors Reference
Typical fouling resistance (Rd) values for common process fluids in shell-and-tube heat exchangers. Fouling resistances derate the clean U-value for preliminary sizing.
Minimum Approach Temperature Reference for Heat Exchangers
Typical minimum approach temperature values for common heat exchanger services. The approach temperature controls the trade-off between heat transfer area and energy recovery.
Heat Exchanger Sizing Under AS 1210 Reference
High-level educational overview of how AS/NZS 1210 (Pressure Vessels) relates to heat exchanger sizing in Australian and New Zealand projects. Covers the interaction between AS 1210, AS 3857, and TEMA standards.
Heat Exchanger Design Margin Reference
Practical reference on area margin and design factor for preliminary heat exchanger sizing — typical ranges, when to apply more or less margin, and how project standards and uncertainty affect the choice.
Heat Exchanger NTU Effectiveness Reference
Reference-style context for the NTU/effectiveness method — common flow arrangements, typical ε–NTU relationships, dimensionless groups (NTU, C*), and how NTU concepts support preliminary heat exchanger checks. Not a design chart and not a calculator.
These references provide typical engineering values with source citations for preliminary heat exchanger sizing. They are not design values and should be confirmed with detailed thermal-hydraulic design or vendor data before procurement. Additional references will be added as the heat exchanger sizing cluster expands.
