Content Errors

• page 7, next to last paragraph, 4th line,  "force increases rapidly as radial distance DEcreases"
• page 19, first line of solution to example 1.5 should read  ....range 1 MPa < P < 1.2 MPa.
• page 23, problem 1.3, part f, should read "Repeat part e...",  part g, strike the word "isobaric".
• page 41, Eqn in center of page following eqn 2.34, should have a minus sign on the left hand side, = - B(T+273.15)^2/(T+C)^2.
• page 53, Eqn 2.53, V = RT/P which becomes...
• page 55, Example 2.12, first eqn labeled (ig), "(Cv/R)dT/T=dn/n " ; the R is missing.
• p 62 problem 2.11, all flowrates are in kg/min.
• page 69, second full paragraph, in listing of arrangements for three particles, 1-3-2 is ommitted, and 2-3-1 is listed twice.
• page 100, problem P3.2, Last sentence should read "Compute DeltaS/k."
• page 100, problem P3.3, Last sentence should read "Compute DeltaS/k."
• page 104, problem 3.23, the turbines are incorrectly drawn as compressors.
• page 112, Example 4.3, Rankine with reheat, the pump work was ommitted from the net work in the calculation of thermal efficiency. The net work is 1349 kJ/kg, eta = 1349/3695 = 0.365, m dot = 2670 kg/h.
• page 137, Example 5.5, there is a sign error; the equation for dS should read dS = CpdlnT - R lnP -B1dP, and the equation for DeltaS should read DeltaS = Cpln(T2/T1) - R ln (P2/P1) - B1*DeltaP.
• page186, Eqn 7.33,  multiply right-hand side by -1. (11/4/98)
• page 201 Example 8.2 and 8.3, the vapor pressure should be given as 0.324 MPa
• page 208, there is an error in the calculations leading to the figures. To obtain a replacement page, using lnj = lnj⁰ + wln j¹, click here.
• page 251 Equations for phi hat just above 10.19, the lower case p should be an upper case P.
• page 275, example 11.1 at top of page, chemical potential in first two lines should be excess chemical potential. (11/3/98)
• page 282, Eqn 11.26 can easily be misinterpreted. the equations are more clearly written as

A₁₂ = [   ]² * ln(gamma1), A₂₁ = [   ]² * ln(gamma2), where the quantities in [ ] are as given.
• page 285, example 11.7 When the activity coefficients for cyclohexane are calculated for the second and third iterations, the temperature ratio that appears is not used.
• page 381 Eqn 15.32, the absolute value operator should be removed. As written the equation is valid for any reaction where the reaction coordinate is positive. It can be used for reverse reactions if the absolute value operator is removed.
• page 461,

2nd integral, the b^2 should be a b, should read Int(x^2dx/(ax+b)) = x/a - b*ln(ax+b)/a^2
4th integral should be int(x3dx/(ax+b))=[ (ax+b)^3/3 - 3b*(ax+b)^2/2 +3b^2*(ax+b)-b^3*ln(ax+b) ]/a^4
6th integral should be - instead of + on the ln term.
8th integral should be -b^2 instead of -b^3 in second term.

• PREOS.xls, Props page, cell K4 should be =J4-_R*(T-TREF). The cell is not used in subsequent calculations.
