Q2: Reduce the block diagram of Fig (2). to single block and find the system transfer Y(s) Flexible function- R(s) Rigid R(s)

Can a tank with the outflow rate fixed by a constant speedpump reach a steady state if the inlet flow rate undergoes astep change? Why, or why not? If the transfer function is G(s)=K/s, is it possible to calculate a steady-state gain?

Draw (a) and (b) dynamic response.

4.13 A horizontal cylindrical tank shown in Fig. E4.13a is used to slow the propagation of liquid flow surges in a processing line. Figure E4.13b illustrates an end view of the tank and w, is the width of the liquid surface, which is a function of its height, both of which can vary with time. Develop a model for the height of liquid h in the tank at any time with the inlet and out- let volumetric flow rates as model inputs. Linearize the model assuming that the process initially is at steady state and that the liquid density p is constant.

B) If the forward function for a control system is given below, and the feed backward is unity. Find the range of (K) that make this system stable: G(s) = K(S² + 3S+4) S(S+2)(S²+2S - 3)

Answer them all.  Process Control and Instrumentation.  Thank you!

how to find the lost work? which eqn should I use? Pls help me. Thank u,

Example 2: Draw the Bode plot of the unity feedback system with forward gain as G(s) = 40 (8+2)(8+5) Also determine the gain margin, phase margin and comment on the stability of the system.

5.11 A process of unknown transfer function is subjected to a unit impulse input. The output of the process is measured accurately and is found to be represented by the function Y(t) = t e¹. Determine the unit step response in this process.
