A wastewater plant followed standard Joukowsky equation (ΔP = ρ a ΔV) and predicted a 120 psi surge. The showed 280 psi because entrained air collapsed near the check valve. Lesson: The book’s appendices include gas-release transient tables—ignored in 90% of surge analyses.

A mining operation wants to reduce energy costs on a long-distance slurry pipeline. The Solution: Using the Slurry transport section of the HI Data Book, you cross-reference the particle size distribution versus the critical settling velocity. You realize the current velocity is 20% higher than necessary. By reducing the flow rate (and friction loss) using the pipe friction charts, you save 150,000 kWh annually.
