Process Control: Modeling, Design, and Simulation

Student Exercises

1:	Consider the gas drum in Example 2.1. Often the outlet flow relationship is actually nonlinear, with the form so the modeling equation is Discuss whether this is now a self-regulating process. Also, sketch the steady-state input (qis) -output (Ps) curve, based on the flow coefficient, β = 1 mol · s−1 · atm−1/2 and a constant header pressure, Ph = 1 atm.
2:	Consider the heated mixing tank example, which had the modeling equations For steady-state inlet and outlet flow rates of 100 liters/minute, a liquid volume of 500 liters and ...
