Chapter 1 Introduction
1.1 A gas at 20C may be rarefied if it contains less than 1012 molecules per mm3. If Avogadro's number is 6.023E23 molecules per mole, what air pressure does this represent? Sol
Chapter 10 Open Channel Flow
10.1 The formula for shallow-water wave propagation speed, Eq. (10.9) or (10.10), is independent of the physical properties of the liquid, i.e., density, viscosity, or sur
Chapter 8 Potential Flow and Computational Fluid Dynamics
8.1 Prove that the streamlines (r, ) in polar coordinates, from Eq. (8.10), are orthogonal to the potential lines (r, ). Solution: The streaml
Chapter 7 Flow Past Immersed Bodies
7.1 For flow at 20 m/s past a thin flat plate, estimate the distances x from the leading edge at which the boundary layer thickness will be either 1 mm or 10 cm, fo
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 diamete
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-dime

Find the shear and normal stresses on plane AA cutting t
Chapter 11 Turbomachinery
11.1 Describe the geometry and operation of a human peristaltic PDP which is cherished by every romantic person on earth. How do the two ventricles differ? Solution: Clearly
