PHYS 2 Chapter Notes - Chapter 12.4 - 12.6: Laminar Flow, Turbulence, Mass Flow Rate
Document Summary
Ideal fluid = a fluid that is incompressible. Flow line = path of an individual particle in a moving fluid. Steady flow = a flow in which the overall flow pattern does not change with time. Each element passing through a given point follows the same flow line. Streamline = a curve whose tangent at any point is in the direction of the fluid velocity at that point. When the flow pattern changes with time, the streamlines do not coincide with the flow lines. Flow tube = the tube formed when the flow lines pass through the edge of an imaginary element. Laminar flow = when adjacent layers of fluid slide smoothly past each other. Turbulent flow = when flow rates are high enough or when boundary surfaces cause abrupt changes in velocity of area. The mass of a moving fluid doesn"t change as it flows. For incompressible fluid: is the cross-sectional area of flow tube at two points.
