Find % Conversion for PFR & CSTR Design w/o Eq.

[kritbordin]

The Quastion are giving me a graph ploted between 1/-r and X the graph if perfectly parabola but scale between % conversion are not equal. what sould i do if i asked to find the % conversion for PFR and CSTR which has fix volume.

if u don't clearly understand what I'm ask u may look up at http://www.engin.umich.edu/~cre/02chap/frames.htm .i have been plot the new graph by excel,it came out to be not a perfect parabola, now my problem is i don't really know how to find the inteval of the graph w/o eq. of that graph

it is important to accurately determine the % conversion for PFR and CSTR designs without using the equation. One approach to finding the % conversion would be to calculate the area under the curve of the graph using numerical integration methods. This can be done using software such as MATLAB or by hand using numerical techniques such as Simpson's rule or the trapezoidal rule.

Another approach would be to use the graph to estimate the % conversion at specific points along the curve, such as at the maximum point or at certain intervals. This method may not be as accurate as numerical integration, but it can provide a rough estimate of the % conversion.

It is also important to note that the non-uniform scaling of the graph may affect the accuracy of the % conversion calculation. In this case, it may be helpful to adjust the scaling of the graph to make it more uniform before performing any calculations.

Overall, it is important to carefully consider the limitations and potential sources of error when determining the % conversion for PFR and CSTR designs without using the equation. It may be helpful to consult with a colleague or mentor for guidance and to double-check any calculations or estimates.
