Polymath program

The POLYMATH program and its graphical caitputs are shown in Table E8-11.1 and Kgures E8-1U and E8-U.2. 

A copy of POLYMATH is provided on toe CD-ROM for the students to use to solve the homework problems. The example problems that use an ODE solver (e.g., POLYMATH) are referred to as "living example problems because the students can load the POLYMATH program directly onto their own computer in order to study the problem, Stu-... 

The POLYMATH program and solution are shown in Table E6 7.I. The problem was solved for different values of t and the results are plotted in Figure E6-7.1,... 

The corresponding POLYMATH program written for this probiem is shown in Table E6-3.1 and a plot of the output is shown in Figure E6-8.1. One notes that diere is a maximum in the concentration of NO (i.e., C) at approximately 1.5 dm. ... 

We could have also solved diis problem using POLYMATH or some o er ODE solver. The POLYMATH program using Equations ES-6.I), (Eg-fi.lO), (ES-6.7), (E8 6.il), (E8-6.12), and(E8-6.13) is shown in Table E8-6.2. The graphical output is... 

See Table E8-7,l for a summary of the calculations and Table ES-7.2 and Figure ES-7.J for the POLYMATH program and its graphical output.

We see that five steady states (SS) exist. The exit concentrations and temperatures listed in Table E8-12.2 were interpreted from the tabular output of the POLYMATH program. 

The POLYMATH program and solution are given in Tables E3-8.2 and E3-8.3. The eqitilibrium conversion in a constant-volume batch reactor is... 

Equations (E4-9.il) through (E4-9.13) can now be solved numerically, preferably by a software package such as POLYMATH or MATLAR The POLYMATH program and solution are given in Table FA-9.1 forj A = 2.7 min-, Kc = 1.2mol/dm, and Fao = 10 moFmin, The MATLAB program is included on the CD-ROM. 

The entering volumetrie flow latE is 100 dmVmin and the entering concentration of A is 3 W, What is the CSTR reactor volume (Am. 4000 dm, ) Write a Polymath program to calculate the exit coneentrations when the vol-UTE is given as 6[Pg.326]

Hint The Living Exatrq)le Polymath Program is on the CD ROM P6-30c Read over the oscillating reaction module. For the 4 reactionsinvolving I-... 

What if. .. play around with the Living Example Polymath Program on the CD ROM - what are the effects of changing the values of lq Iq, kj, and k2 Can you make the oscillations damped or unstable ...
