Question
1. (a) Find the transfer functions HylQ and Hy/Q for the three-tank system shown in Fig. P6-4 where Hz, Hy, and Q are deviation variables. Tank 1 and tank 2 are interacting. (b) For a unit-step change in q (that is, Q = 1/s), determine Hg(0) and Ha(), and sketch H3(1) versus t. R =2 Rg =2 Tank 1 Tank 2 Az=0.5 Ry=4 Tank 3 2. In the two-tank mixing process shown in Fig. P6-6, x varies from 0 lb salun' to 1 Ib saltun according to a step function. At what time does the salt concentration in tank 2 reach 0.6 lb salufn? The holdup volume of each tank is 6 f°. 3 f/min Tank 1 Tank 2 FIGURE P6-6
