1. Errors/ misprints/ typos (= less serious misprints)/ clarifications
- p. 33, footnote 14 (MISPRINT): GJ should be MJ (two places)
- p. 36, line 13 (MISPRINT): Margaret Bradley died in 2004 and not 1984.
- p. 72, expression for xA (MISPRINT). Should be xA = (nA1-nA2)/nA1
- p. 136, lines 5-7 in comment no. 7 (MISPRINT): Replace dT_m by dT_lm (3 places).
- p. 145, third line below (6.4) (MISPRINT): "for an ideal" should be "for an ideal gas"
- p. 165-166. Integration limits for T and T_0 should be interchanged in (7.9), (7.15) and (7.16)
- p. 166, equation (7.16). Last T in the equation should be dT.
- p. 175, below (7.22) (TYPO): Delete "Comment on ideal gas assumption" (this is a comment on the origin of the equilibrium constant K and has nothing to do with ideal gas...)
- p. 200, below eq. (8.3) (TYPO). Should be T_H >> T_C (and not T_H >> T_L)
- p. 203 (CLARIFICATION): Ooops, I fell into my own trap...
For the Otto cycle, I refer to |W|/|QH| as a "thermodynamic efficiency" but
it should be called a "conversion factor" (from heat to work).
Comment: This is because I argue
(e.g., in the footnote on page 200) that a thermodynamic "efficiency" should always be between 0 and 1 and it
should be 1 for a reversible process. In general, for a heat engine the maximum value of
|W|/|QH| is the Carnot factor = 1 - TC/TH.
In the Otto cycle heat is supplied at constant volume (and not at constant temperature)
and this gives that the maximum value of |W|/|QH| is mainly limited by the compression (pressure) ratio.
- p. 204 (MISPRINT): The order of equations (8.9) and (8.10) should be reversed to agree with the text above.
- p. 208 (TYPO): 1908 should be 1980 in the second to last line.
- p. 242, unnumbered equation at middel of page (MISPRINT). First square root should be: sqrt(2 / (A1^2/A2^2-1)). i.e., I have multiplied by sqrt( (A1^2/A2^2-1) instead of dividing.
- p. 244, Example 9.2. The exponent for Cd in the equation for DP should be -2, and then the last equation becomes Cd = sqrt(2/n).
- p. 260, 3rd line before Section 10.2 should read (MISPRINT): autocatalytic reactions OFTEN DISPLAY "strange" behavior
- p. 286, Figure 11.6 (MISPRINT). Label on x-axis should be time rather than tid
- p. 320 (ERROR). The Matlab statement x1=n1/n is only OK if the vapor holdup is negligible (i.e., nL >> nG). For this example this is almost OK, but in general we need to add a sixth algebraic equation for the component holdup and add a corresponding algebraic state x1; see the corrected Matlab code flash.m in the Matlab directory on the book's home page.
- p. 388, 3rd line (TYPO): defin/Althtion should be definition
- p. 424, Solution to Exercise 8.4 (b) (MISPRINT): -3.3 MJ should be 1.71 MJ
- p. 416 (MISPRINT.) For C2H5OH (ethanol) the correct boiling point is 355.6 K and dvapH=35.18 kJ/mol
2. Further comments
p.179-p.196; p. 320. NEW MATLAB routines that use the SRK equation of state
( srksis.m )
are now available.
These can be used to simulate dynamics flash
( flashsrk.m )
bubble point
( bubsrk.m ),
PT-flash
( flashPTsrk.m ),
PH-flash
( flashPHsrk.m ),
etc., etc.. Good luck and thanks to Andreas Linhart for providing the
basis for the srksis.m routine!

Carl Sandrock from South Africa thinks the airplane lift example is misleading (but he likes the paper sheet example!).
