Q1. The liquid-level process shown in Figure below is operating at steady state of 10 cfm when the following disturbance occurs: At time t=0, the flow rate of liquid is increased to 12 cfm (unit step); at t =2 min, 1 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= 1.5, 2, and 2.5 min. 10 cfm h Disturbance T = 2 min * R = 0.8
