A Process Control Question Please show the solution. Please solve this question, it's an exam question !!!! In steady state, fluid is fed to the 1st tank with a flow rate of Q0 = 4m3 /min. The fluid with Q1 flow rate from here flows to the 2nd tank as non interaction and exits from the 2nd tank with a flow rate of Q2. In steady state h1 = 4m, h2 =2m. The cross-sectional area of both tanks is 2 m2. At t=0, 4m3 of water suddenly is being emptied the 1st tank. Accordingly, calculate the changes in the output flow rate of Q2 at t = 0, 0.5, 4th minutes ? (Please solve it by show the steady and unsteady state equations.)
