resistance R1 with source pressure P1. F2 is output flow through resistance R2 and flowing out at pressure P2. As the flows into and out of the tank are both influenced by the tank pressure‚ both flow resistances affect the time constant. A typical control problem would be to manipulate one flow rate (either in or out) to maintain a desired drum pressure. Variables: Controlled variable: P Manipulated variable: F2 Disturbance variable: F1 Here we develop a model that describes how the tank pressure
