(Solved): A constant-volume CSTR can be described by the following differential equation: dtdcA=VFi ...



A constant-volume CSTR can be described by the following differential equation:
\[
\frac{d c_{A}}{d t}=\frac{F_{i}}{V}\left(c

A constant-volume CSTR can be described by the following differential equation: where is the concentration in the reactor and is the inlet flow rate. (a) Determine the steady-state concentration for fixed values of and (b) Linearize this equation and recast in terms of deviation variables for and . (c) Find the transfer function that relates the inlet flow to the outlet concentration . NOTE: The input is and the output is . You can also assume that the inlet concentration is fixed.
