By Fox, McDonald & Pritchard
Corrections in the Text
Example Problem 3.5 (page 70):
In the problem statement the resultant force is FR not .
Example Problem 3.7 (page 77)
The first line of SOLUTION: should say “locations” not “directions”
Example Problem 4.10 (page 131)
The first line of the boxed statement should say “apply” not “evaluate”
Example Problem 5.8 (page 210)
The blue color on page 210 was not printed rendering the page difficult to interpret. The corrected page looks like (see next page):
Example Problem 8.11 (page 366):
The analysis is correct except there is a repeated numerical error: the computations of relative roughness for all pipes are incorrect by a factor of 144. This means all subsequent calculations are in error.
On page 367 the graphic should be:
with the total error on the last line of the page as 735%, not 665%.
On page 368 the graphics should be:
and
On page 369 the tabulated flow rates should be:
QA = QC = QD = 167 gpm (not 260 gpm)
QB = 72 gpm (not 112 gpm)
QE = QH = 95 gpm (not 147 gpm)
QF = 24 gpm (not 37 gpm)
QG = 71 gpm (not 110 gpm)
Fig. A.2 (page 722):
Absolute viscosity, (N.s/m2) not Absolute viscosity, (N.s/m2)
Corrections in Problem Statements
Problem 8.103 (page 398): The flow rate range is 1 L/min through 10 L/min not 1 L/s through 10 L/s
Problem 8.136 (page 403): The fluid is water
Problem 10.12 (page 575): The impeller exit diameter is 300 mm not 150 mm
Problem 10.46 (page 579): The fluid is water
Problem 10.50 (page 579): Estimate the maximum allowable flow rate not speed
Problem 11.13 (page 613): Increase the balloon radius not diameter from 5 to 7 inches
Problem 12.44 (page 704): Assume isentropic flow
