19. A sinking body (such as a rock in a pond) does not experience a buoyant force. 20. For a submerged body, if the body CG is located above the center of buoyancy, the body is unstable. 21. Pathline is a concept related to Lagrangian description of a flow. 22. A photo of a cigarette smoke shows the streamlines. 23. For a steady incompressible flow, streamlines look the same as Rathlines. 24. If there is no flow, the substantial derivative of fluid temperature is equal to the local time-derivative of temperature. 25. The water flow through a garden hose can be assumed to be steady flow.
