How this estimate is computed

Turton/CAPCOST purchased-cost correlation, escalated by the CEPCI index:

log₁₀ Cp° = 3.3892 + 0.0536·log₁₀ A + 0.1538·(log₁₀ A)² · × CEPCI 820/397 (A = shaft kW, valid 1–300)

Correlation: Turton et al., Analysis, Synthesis and Design of Chemical Processes, Appendix A (CAPCOST) — centrifugal pump + driver, published coefficients.
Escalation: CEPCI 397 (2001) → 820 (2026, Chemical Engineering index).
Installed cost: Hand's published per-equipment factor (pumps ×4) — includes piping, electrical, instrumentation and erection share at screening level.
Cost basis: open cost book turton-open-equipment v1.1.0.

Screening is level 1. Negotiation needs level 2.
