The liquid-level process shown below is operating at a 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. Determine the level in feet at t = 0.4 if at t<0 h=1.77. 10 cfm Disturbance r = 1 min R=0.5
