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, for (a) air; and (b) water at 20C and 1 atm. Soluti
Chapter 9 Compressible Flow
9.1 An ideal gas flows adiabatically through a duct. At section 1, p1 = 140 kPa, T1 = 260C, and V1 = 75 m/s. Farther downstream, p2 = 30 kPa and T2 = 207C. Calculate V2 in m/s and s2  s1 in J/(kg K) if the gas is (a) ai

Chapter 10 Open Channel Flow
10.1 The formula for shallowwater wave propagation speed, Eq. (10.9) or (10.10), is independent of the physical properties of the liquid, i.e., density, viscosity, or surface tension. Does this mean that waves propagate

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 we are speaking of the human heart, driven period
Chapter 2 Pressure Distribution in a Fluid
2.1 For the twodimensional stress field in Fig. P2.1, let
xx = 3000 psf yy = 2000 psf xy = 500 psf
Find the shear and normal stresses on plane AA cutting through at 30. Solution: Make cut "AA" so that
