WebFeb 18, 2013 · From a mole balance we know that at steady state \(0 = F_{A0} - F_A + V r_A\). That equation simply states the sum of the molar flow of A in in minus the molar flow of A out plus the molar rate A is generated is equal to zero at steady state. This is directly the equation we need to solve. We need the following relationship: \(F_A = v0 C_A\) WebCOMPARE WITH CSTR RESPONSE TO TRACER PULSE DISPERSION 0 Q C O Q C L L 0 time 0 time . 2 In an ideal PFR, concentration is a function of both distance along the flow ...
