Chapter 5 Dimensional Analysis
and Similarity
5.1 For axial flow through a circular tube, the Reynolds number for transition to
turbulence is approximately 2300 [see Eq. (6.2)], based upon the diameter and average

Chapter 4 Differential Relations
for a Fluid Particle
4.1
An idealized velocity field is given by the formula
V = 4txi 2t 2 yj + 4 xzk
Is this flow field steady or unsteady? Is it two- or three-dimensional? At the point (x, y, z) =
(1, +1, 0), compute (a)

Water ﬂows steadily through the
round pipe in the ﬁgure. The entrance
velocity is V0. The exit velocity
approximates turbulent ﬂow, u =
umax(l — r/R)1/7. Determine the ratio
Uo/umax for this incompressible ﬂow.
Solution: Inlet and outlet ﬂow must balanc
