2- A stirred-tank blending system initially is full of water and is being fed pure water at a constant flow rate, q. At a particular time, an operator shuts off the pure water flow and adds caustic solution at the same volumetric flow rate q but with concentration If the liquid volume V is constant, the Ci dynamic model for this process is: dc V + qc = qc dt With c(0) = 0 What is the concentration response of the reactor effluent stream, c(t). Solve using Laplace Transform and Laplace Inverse. Sketch it as a function of time. Data: V = 2 m3; q = 0.4 m3/min; = 50 kg/m3 Ci
