BOOK IN SERIES Hydraulic Nonlinear Resistances in Parallel: Figure 1.10 shows three hydraulic valves in parallel. Equations 1.11A, 1.11B and 1.11C show how to calculate the equivalent valve coefficient for valves in parallel C vep . The calculation is based on the following two facts:  The differential pressure across the valves in parallel is the same.  The total flow through the valves equals the sum of the flow through each valve in parallel. ∆ ∆                        .           .   ∆            .  88 Fig. 1.11 - Nonlinear Hydraulic Resistances in Parallel www.ghmediabusiness.com
