This Fluid Mechanics For Plant And Piping Engineers eBook from 3D-LABS is written for engineers and students who want a clear, practical reference they can apply immediately.
This e-book covers fluid mechanics specifically for process plant and piping engineers: pipe flow calculations, pump sizing, two-phase flow, pressure relief valve sizing, and compressible flow — all referenced to ASME B31.3, API RP 520 (Part I), API RP 521, and ISO 4126. It bridges the gap between academic fluid mechanics and the actual calculations required on an EPC piping isometric package.

Frequently Asked Questions
What pipe flow formulas are covered in this book?
The book covers: Darcy-Weisbach (ΔP = f × L/D × ρV²/2, where f from Moody chart or Colebrook-White equation), Hazen-Williams (V = 0.8492 × C × R^0.63 × S^0.54 for water), Manning equation for open channels, and the API RP 14E erosional velocity limit (Ve = C/√ρ, C = 100 for continuous service, C = 125 for intermittent per API RP 14E Clause 2.4c).
How does this book cover pressure relief valve sizing?
PSV sizing per API RP 520 Part I (10th Ed., 2020): for vapour service A = W/(CKdP1Kb√(M/TZ)) and for liquid service A = Q/(38Kd × Kw × Kc × √(ΔP/G)). The book covers fire case sizing per API RP 521 (7th Ed., 2020) and the 10 overpressure scenarios in API RP 521 Annex A that must be evaluated for every process vessel.
What two-phase flow correlations are included?
Lockhart-Martinelli correlation for horizontal two-phase pipe flow (void fraction and pressure drop), Baker chart for flow regime identification, and the Beggs-Brill correlation for inclined two-phase flow — the method used in PIPESIM and OLGA process simulators. The book explains when each applies and how to select the conservative correlation for safety systems.
