Pascal’s law: Pressure applied to an enclosed fluid is transmitted undiminished to every portion of the fluid and the walls of the containing vessel © 2005 Pearson Education

14.3 Buoyancy © 2005 Pearson Education Archimedes’s principle states: When a body is completely or partially immersed in a fluid, the fluid exerts and upward force on the body equal to the weight of the fluid displaced by the body

12
Ideal fluid: fluid that is incompressible and has no internal friction Ideal fluid: fluid that is incompressible and has no internal friction Flow line: The path of an individual particle in a moving fluid Flow line: The path of an individual particle in a moving fluid Steady flow: If the overall flow pattern does not change with time Steady flow: If the overall flow pattern does not change with time Streamline: is a curve whose tangent at any point is in the direction of the fluid velocity at that point. Streamline: is a curve whose tangent at any point is in the direction of the fluid velocity at that point. © 2005 Pearson Education

14.6 Viscosity and Turbulence Viscosity is internal friction in a fluid Viscosity is internal friction in a fluid When the speed of a flowing fluid exceeds a certain critical value, the flow is no longer laminar. Instead, the flow pattern becomes extremely irregular and complex, and it changes continuously with time; there is no steady-state pattern. This is irregular, chaotic flow is called turbulence When the speed of a flowing fluid exceeds a certain critical value, the flow is no longer laminar. Instead, the flow pattern becomes extremely irregular and complex, and it changes continuously with time; there is no steady-state pattern. This is irregular, chaotic flow is called turbulence © 2005 Pearson Education
