Unformatted text preview: equation we will use to design PFRs at steady <tare can be developed in two ways: ( I ) directly from Equation (1-4) by differentiating with respect to i,olume V, or ( 7 , ) froin a inole balance on species j in a differential segment of the reactor volume A\'. Let's choose the second way to arrive at the differen- tial form of the PFR mole balance. The differential volume. A V , shnwn in Fig- ure 1-10. will be chosen sufficiently small such that there are no spatial variations in reaction rate within this volume. Thus the generation term.
