Velocity Profiles and Friction Factors in Turbulent Pipe Flows,r ducts are also treated in this chapter. Not all pipes are smooth, and in reality, they have a certain level of surface defects marked by protrusions or indentations. Expression for fully developed velocity profiles in rough straight circular pipes is presented as well.

Drag Reducing Agents: A Historical Perspective,and surfactants. It reviews past work on this subject and provides a historical perspective about this phenomenon. The chapter also discusses the proposed theories of drag reduction indicating how the extent of drag reduction lies between the Blasius line and the maximum drag reduction asymptote. An

Turbulent Forced and Mixed Convection Heat Transfer in Internal Flows, well estimated without solving the energy equation using momentum/heat transfer analogies. Expressions for the local Stanton numbers are derived for external flow (vertical pipes) and internal flow (circular pipes) using the analogy. An approximate theoretical analysis of the effect of buoyancy on

Natural, Forced, and Mixed Convection Heat Transfer in External Flows Through Porous Media,plate embedded in a porous medium. The final form of the equation for mixed convection is like those of the correlating equations for combined laminar forced and free convection heat transfer for Newtonian fluids and for non- Newtonian fluids in homogeneous media. Such equations which interpolate th
