Fluid Mechanics, 4th Edition, by Frank M. White

NOTES ABOUT ERRATA IN THE FIRST PRINTING (not necessarily in order, as new corrections are added to the end of the document):

Page 51, Problem 1.62, line 2:

“If the hydrogen-water interface...” (not ‘hydrogen-air)

Page 88, Eq. (2.52): When changing to blue, the first denominator vanished:

(Presently, the denominator tan( is missing – it was there in Final Proofs.)

Page 186, Problem 3.18, last line: add data for b and h:

Add data: “...estimate umax in m/s for b = h = 10 cm.”

Page 187, Problem 3.25, next-to-last line:

Change Δu to ΔU: “...Find ΔU as a function of stream speed...”

Page 189, Problem 3.36, line 2: add ‘-in-’ (for inch)

“...through a 3-in-pipe and entrains...” (not ‘ 3-pipe’ )

Page 205, Problem 3.150, the equation “hf ( ...” needs a subscript “1” on V:

Page 409, Prob. 6.58, the very bottom of the right column:

“... and (z = 100 m....” (not (x = 100 m)

Page 458, Table 7.2, bottom, elliptical cylinder. Numbers on the left side of the

figures should have a colon, not a decimal point:

1:1 , 2:1 , 4:1 , and 8:1 (not 1.1, 2.1, 4.1, 8.1)

Page 500, Eq. (8.17): Second integral should have d(, not d(:

Page 551, Eqs. (8.199abc): Compositor failed to restore all denominators:

Page 613, line 12: the second “1” should be a plus sign (+):

fLD1 = fLD2 + DeltafLD , not “= fLD2 1 DeltafLD”

Page 627: Add an EES Icon to the Solution to Example 9.17.

Page 641, Problem 9.9, line 3, change ‘at an exit pressure equal to’:

to: “at Vexit = 1600 m/s to an ambient pressure of 54 kPa.”

Page 647, Problem 9.80, Forgot to specify the tire volume:

“...thousandths of an inch. The tire volume is 2.5 ft2.

Page 762, Problem 11.70, last line, add data:

“...what is the flow rate if d = 8 inches.”

FURTHER ERRATA IN THE 1st PRINTING, discovered by Christoffer Norberg

p. 67, line 1 below Fig. 2.6: ... and p2 = pa at z2 = 0: (subscript a , not z)

p. 138, line 10: “...double-integral flux terms required...” (not triple-integral)

p. 169, Fig. E3.18, near top arrow: should be (s = 700 hp, (not (s).

p. 180, Eqs. (2) and (3) need negative signs:

p. 181, equation below Eq. (1) and the sentence “We relate...”:

A1V1 = A2V2

V1 = (2V2 (not (2V2 )

p. 232, Eq. (4.47); Minus sign before the square bracket: (v = - [......

p. 233, 4 lines below Eq. (4.50); ...using the linear-momentum equation (4.32)

p. 240, line 8: ...as follows. From Eq. (1.41) the definition ...

p. 256, Fig. 4.15, left side: just plain U ( not U( ).

p. 294, last term of Eq. (5.25) should have a minus sign:

p. 330, line 19: ... no analyses which can simulate the fine scale random ...

p. 339, Eq. (6.26): reverse the subscripts on V: ... = ((V2 – V1) = 0

the ith vortex to the point (x,y) should be labeled ri , not rt.
