Total No. of Questions : 10] [Total No. of Pages : 3 P1095 [3864]-364 B.E. (Petrochemical) PROCESS DYNAMICS AND CONTROL (2003 Course) Time : 3 Hours] [Max. Marks : 100 Instructions to the candidates: 1) Answer three questions from each section. 2) Answers to the two sections should be written in separate books. 3) Figures to the right indicate full marks. 4) Use of logarithmic tables, slide rule, electronic pocket calculator and steam tables is allowed. 5) Assume suitable data, if necessary. SECTION - I Q1) a) Discuss importance and usefulness of Process Control - Explain with help of suitable example. [8] b) Develop the overall Transfer Function of two interacting tanks placed in series. Discuss the dynamics of the system. [8] Q2) a) Solve the differential equation with help of Laplace Transform : [6] d2y dy y = 15 where y' (0) = 0 and y(0) = 2 4.5 2 + 13.63 dt dt b) Develop overall transfer function of any 1st order system. In this context highlight importance of Gain. c) [6] Define following with help of neat diagrams : [4] Overshoot, Damping factor. P.T.O. Q3) a) b) c) Q4) a) b) Q5) a) b) Discuss the merits and Demerits of Feed-forward and Feed-back Control loops. [6] For a liquid level system as shown below, cross-sectional area of tank = 3.0m2. The valve characteristics is given by qout = 13.5 h.[6] Where, qout is flowrate in m3/h at outlet and h denotes level of liquid above tank in m. Calculate the time constant for the system if the average operating level is 9m. What is linearlization? Develop an linearlized expression for the following square root relationship [6] q = C (h)1/2 where, q is flow rate, C is a constant and h denotes height. What are Servo and Regulatory control problems - Discuss the transfer functions with help of neat diagram. [8] With help of neat sketch explain the proportional, derivative and integral modes of a PID controller. [8] For the control system represented by characteristic equation [8] s4 + 4s3 + 6s2 + 4s + (1 + K) = 0 Determine the maximum value of gain K which leads to a stabilized operation. Find the overall transfer function of the following system. [8] [3864]-364 2 SECTION - II Q6) a) b) Q7) a) b) Q8) a) b) Q9) a) Draw Root locus Diagram for the following closed loop transfer function. Comment on the stability of the system. [9] Draw Bode Plot for the following system : 20 (10s + 1)-1 (s + 1)-1. Discuss in details the procedure and precautions of Zeigler Nichol controller Tuning method. [8] Oil and water are to be separated based on their differences in density. Develop a programmable logic control (PLC) algorithm for this industrially important process. [8] Explain Cascade Control Scheme for a shell and tube heat exchanger. [8] With help of sketch explain transformations of Discrete Signals to Continuous and vice-versa. [8] Calculate Amplitude Ratio and Phase Angle for overdamped 2nd order 12 . ( 4s + 1)(6s + 1) Explain the poles and Zeros of the Transfer Function. system with transfer function : G(s) = b) [9] Q10)Write short notes on (any four) : a) Ratio Control. b) Gain Margin and Phase Margin. c) Negative Feedback and Positive Feedback. d) Distillation Column Control. e) PLC based Control. vvvv [3864]-364 3 [8] [8] [16]
