Here are some additional notes on some stuff we will be talking about from Chapter 5, here is some info on Example 5.7 , and here is stuff regarding the derivation and solution of equation 5.35 , noteseqn5.35 . Also here are additional details on solving Equation 5.37, noteseqn5.37 .  Mass transfer in a rectangular conduit which is similar to the analysis shown in Example 5.10 for a tube of arbitrary cross section, Mass Transfer in a Parallel Plate Channel . Also here is another example that builds on Example 5.10, example5.10addition .  Here is some info on the derivation of equations 5.5 and 5.49 equations5.5and5.59 . Some additional notes on Figure 5.9 Notes on Fig. 5-9 Here are some additional notes on problem 5.11 prob5.11notes . Here is the mathcad solution for Example 5.15, Example 5.15 .

47618__a-joke-by-sheldon-cooper_pHere is an example of how to solve a first order ordinary differential equation using Matlab. The function in this case is that  dy/dx = – 3 y with the boundary condition that when x = 0 then y(0) = 4. This solution is applicable to solving problem 4.7 where in this case think of the ODE as  dZ/dt = – A V[Z(t)]  and the initial condition is that when t = 0 then Z(0) = 1.3 m. The term A is just a constant that includes all the other variables, make sure your units are all compatible. You would solve this over the time interval from 0 (tstart = 0) to say 100 minutes (tend = 100) and note when Z = 1m which means the bag is empty. Here is the program ODE

For homework #7 work problems 4.27 and 4.47. These problems are due on Monday September 29th. Please note that in problem 4.27 the headings for the columns of data are reversed. Also in the square root heading in the denominator the “n” is really the Greek symbol “nu” which sort of looks like this v.
