Consider the process below: P₁- 65 psig PT 20 P2= 50 psig h(t) SP Yes PIC 20 PY 20 N₂ P3 = 45 psig 1. Define the type of each variable. 2. Assume you were asked to model this process (excluding the control loop), and you would have found the T.F. of the open-loop system. a. How many transfer functions do you expect? b. Suggest a block of the open-loop process based on your answer above in a) c. Draw the block of the closed-loop process shown in the Figure.
