In the application of the governing equations (energy and momentum) for external flow, the assumption of ideal flow is made (see Table 4.1 and Section 10.4). Furthermore, the application of the governing equations for ideal external flow requires the modeling of flow resistance (frictional losses). The modeling of flow resistance requires a “subset level” application of the governing equations (Section 10.3). The distinction between ideal and real flow determines how the flow resistance is modeled in the “subset level” application of thegoverning equations. Explain the assumption of ideal flow and how the flow resistance is modeled.
