Question: The liquid-level process shown in Fig. P5-9 is operating at steady state when the following disturbance occurs: At time t = 0,1 ft3 water

The liquid-level process shown in Fig. P5-9 is operating at steady state when the following disturbance occurs: At time t = 0,1 ft3 water is added suddenly (unit impulse) to the tank; at t = 1 min, 2 ft3 of water is added suddenly to the tank. Sketch the response of the level in the tank versus time, and determine the level at t = 0.5, 1, and 1.5 min. 10 cfm FIGURE P5-9 h Disturbance T = 1 min R=0.5
