Hydraulic — Institute Engineering Data Book

Problem: A chemical plant reported a $30%$ drop in flow rate after three years of operation. The original design used a generic $C$ factor of 130 for the Hazen-Williams equation.

The HI Engineering Data Book provides expanded Moody chart data specifically calibrated for aged piping systems. Unlike academic tables that assume "clean" or "new" pipe, HI data incorporates decades of field measurements. hydraulic institute engineering data book

Outcome: By recalculating the system curve using the HI-sustained $C$ value, the engineer correctly sized a new impeller trim. The pump was restored to its BEP, reducing vibration by $22%$ and saving $$18,000$ annually in electricity. Problem: A chemical plant reported a $30%$ drop
