You can either hand write the units to the axis or use the Microsoft drawing tools to add the units. You will need to edit the graph to label the axis to produce what is shown below. Then use select all and cut and paste the POLYMATH report into a word document as shown below as well as the graph. Note that for equation 1, this should be a sample calculation using your initial guess. Write this calculation on engineering paper as well your hand calculations with units for equations 1, 2, 3, and 5. Estimate the volume using the ideal gas law. In presenting the solution do the following:and produce the printout found on the following page: 1. This is taken from the Cutlip and Shacham text book titled, “Problem solving in Chemical Engineering with Numerical Methods.” The van der Waals equation of state is given by (1) Where (2) And (3) The variables are defined as: The reduced pressure is defined as (4) And th compressibility factor is given by (5) Calculate the molar volume and compressibility factor for gaseous ammonia at a pressure of 56 atm and a temperature of 450 K using the van der Waals equation of state. What did you type? Now review the Non linear Equations solver: Following Example 1 and Example 2 given in the Polymath program tutorial solve the following problem. Have polymath, using the calculator give you the cosine of 30 degrees. How would you have polymath give you the absolute value of a number? 7.
