Document Summary

12. 4 fluid flow: ideal fluid: incompressible, no internal friction (viscosity, flow line: path of an individual particle in a moving fluid, steady flow: the overall flow pattern does not change with time o. All elements passing through a given point follow the same flow line. Fluid velocity remains constant, but individual particles" velocities may change in o direction & magnitude: streamline: curve whose tangent at any point is the direction of the fluid velocity at that point. If flow pattern changes with time, streamlines do not coincide with flow lines in steady o flow: flow tube: tube formed by flow lines passing through edge of imaginary element like area. Flow pattern changes continually o: continuity equation. Example 12. 9: the venturi meter: derive an expression for the flow speed v1 in terms of cross-sections a1 and a2, and the difference in height h of the liquid levels in the two vertical tubes.
