BOOK IN SERIES Linear Resistances in Parallel: Figure 1.9 shows three electrical resistors in parallel and three hydraulic lines in parallel. Equations 1.7 and 1.8 show how to calculate the equivalent resistance in both cases. The calculation in both cases is based on the following two facts:  The effort variable across the resistive elements in parallel is the same.  The total flow variable equals the sum of the flow variables through each element in parallel.    ∆ ∆ ∆ ∆   =   +   +   = + + = ⇒ =               ∆ ∆ ∆ ∆   =   +   +   = + + = ⇒ =                 .  .  Fig. 1.9 - Linear Resistances in Parallel 80 Nonlinear Hydraulic Resistances: Whe Ʌձمٔəɵ́́ɽչѥե܁ѡɽ՝ѡمٔ́)䁄ɕɔɽYٔՙɕ́ɕ́ѡɕͥѥ٥䁽Ʌձمٔ䁄ѕɴ)Yٔ иՅѥĸ́͡ѡɥ䁉ݕѡɕѥɕɔ"ɽ)ѡمٔѡ܁ɅєDɅձեѡЁ́Ʌ٥Mɝمٔ)Ё́ѡم͕ٔ́ɝ܁ȁ͵ɕɔɽ)ܹ̹ͥ
