Homework Set 9
This assignment is to be completed in assigned homework groups. Be sure to include the
group number as well as first and last names of all contributing group members in addition to
the assignment number and instructor name on the submitted homework. The assignment must
be in one person’s handwriting. If you use an equation solving tool (calculator, APEx, Solver,
MATLAB), write out the equation(s) and note the tool that you used; otherwise, show all hand
calculations in equation solving. All problems are from the end of the chapters in the 4th edition
of the Felder, Rousseau, and Bullard (FR&B) text unless otherwise stated.
1. (5 pts) Based on the results of the CATME survey, talk about what changes you plan to
make, as a team and as individuals, on the last two group homework sets.
2. (10 pts) FR&B 8.37
3. (10 pts) FR&B 8.38


Typos in Prob. 8.28.
-- In Line 2, insert an equal sign before (0.7941)
-- On the flow chart, insert mole fraction units for all variables below arrows [mol
H2O(v)/mol and mol dry gas/mol]
-- To the right of the enthalpy table, change Table 8.4 to Table B.5
Typos in Prob. 8.29(a).
-- Insert a rectangular box extending from the right of the two labeled arrows (1284... and
3054...) to the left of the single labeled arrow.
-- Move the two equations beginning with Q, the curly bracket to the right of them, and the
arrow to the right of that up so that the arrow points to the equation beginning with 0.
-- In the equation beginning with 0, change the lower limit of the second integral from 25 to
20.
-- Change the final answer from 44.3oC to 41.4oC.
