MAE 101 UCSD

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 3 velocity. If d = 5 cm and the flu

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), co

Chapter 6 Viscous Flow in Ducts 6.1 In flow past a sphere, the boundary layer becomes turbulent at about ReD 2.5E5. To what air speed in mi/h does this correspond to a golf ball whose diameter is 1.6 in? Do the pressure, temperature, and humidity o

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? Solution: The mass of one molecule of air may be com
