3. Production of a special lubricant is done by heating and mixing a waxy solid with certain liquid hydrocarbons. The control system as shown in Fig.3 below is controlled by PD controller. Assume that there is heat flow between the surrounding and the process. Available data: F300 1/m; V1=4501, V2=375 1; V3=3001 mean heat capacity and density of mixer (liquid and solution) Cp- 0.925 kcal/kg °C and p=0.9 kg/1. Gain of control valve Gv=250 kcal/min/C, G = 1; Kx=1 2 1. 11 Develop the block diagram of control system For servo problem determine the value of gain in (psi/"C) which may just cause the system to become unstable if Tp=0.25 min tigad and solution Minor ming DO "C kcal/min FCE psi IPD Controller Scom Fig. 3
