Question
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 adds caustic solution at the volumetric
but concentration cj. If the liquid volume V is constant, the dynamic model for this
flowrate
process is:
dc
V + gc = qc{
dt
with c(t = 0) = 0.
a. What is the concentration response of the reactor effluent stream, c(t)?
b. Sketch it as a function of time.
Use the following data: V= 2 m³, q = 0.4 m³/min, c; =
50 kg/m³
