This paper presents an electrical model for studying the process behaviour of a sachet water production plant. In this model, the mechanical components of the plant such as the connecting pipes, the water tanks and the water filter were represented by resistors, capacitors and an inductor, respectively. A state equation was developed as a mathematical model of the electrical circuit. In this equation, resistors, capacitors and inductor representing the restriction of the pipes, the capacity of the tanks and the filtration of the filter respectively, were used as variable parameters to generate the state variables of the state equation. This mathematical model was used to simulate the effects of varying the electrical parameters (and) on the state variables ( and) representing the restriction of the connecting pipes, the water levels () in the water tanks and the filtration of the water filter, respectively. Insight into the response curves will indeed form the basis for studying the process control of the sachet water processing plant.
Key words: Mathematical model, analogous system, state equation, control, modeling, simulation
