Pressure slip-tube model

In the following sections, the flow patterns, void fraction and slip ratio, and local phase, velocity, and shear distributions in various flow patterns, along with measuring instruments and available flow models, will be discussed. They will be followed by the pressure drop of two-phase flow in tubes, in rod bundles, and in flow restrictions. The final section deals with the critical flow and unsteady two-phase flow that are essential in reactor loss-of-coolant accident analyses. 

Example 3.4 Flow of a Power Law Fluid in Tubes For an isothermal, laminar, fully developed steady pressure flow of an incompressible Power Law model fluid in a horizontal tube without slip, we wish to derive (a) the velocity profile and (b) the flow rate.
