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 Cvep. 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.
