Zusammenfassung
Strömungsverluste durch Dissipation werden üblicherweise in Form von Widerstandszahlen ζ und Widerstandsbeiwerten cW angegeben, je nachdem, ob es sich um eine Durch- oder eine Umströmung handelt. Die physikalische Interpretation bezieht sich dabei auf das Auftreten eines zusätzlichen Druckverlustes bei Durchströmungen (s. (6.24) für das Beispiel eines 90◦- Krümmers) bzw. einer Widerstandskraft bei Umströmungen (s. Beispiel 9.1 für die überströmung einer ebenen Platte).
