7 | Fluid Systems

By the end of this section, you should be able to

  1. Find analogous resistances, capacitances and inductances in fluid systems

  2. Model fluid systems using electrical analogs

    • Create transfer functions for input/output flows/pressures

  3. Use Simulink to simulate solutions to transfer functions

Electrical Analogs
