Q3. The two-tank heating process shown below consists of two identical, well-stirred tanks in series. A flow of heat, Btu/min, can enter tank 2. A PD controller with (K6 psia per F. to 0.5 min) is used to maintain the temperature in tank 2 at some desired value (T.). Neglect the dynamic lag in measuring and final control elements. An input of 1 psia to the final control element changes heat input to the tank by 500 Btu/min Develop a block diagram of the control system with appropriate transfer function in each block. Each transfer function should contain numerical values of the parameters, Initially, at t-OT. TIET, - 60 °F and 9 -0. The following data apply: w 250 lb/min, hold up volume of each tank 5. density of fluid - 50 lb/n), heat capacity of huid - 1 Btu/ (t) (F). At time to the temperature of the iniet water 1 drops from 60°F to 52°F according to a step function. Determine the dynamic response of the system and the offset.
