Fluids Part1 Dynamic Fluids Incompressible (Volume and Density are constant) Ex: Liquids Compressible (Volume and Density are variable) Ex: Gases Fluids Non-Viscous (Low viscosity) Ex: Water, Gases Viscous (High viscosity) Ex: Honey, Oil Fluids Flow 1. Laminar Flow (Steady, Irrotational and the speed is constant at each point in a uniform pipe) 2. Turbulent Flow (Unsteady flow, rotational and the speed is variable at each point in a uniform pipe) Ideal Fluild It is the fluid which is : 1. Incompressible 2. non-viscous 3. steady flow[ Ex: Water ] Force and Pressure in a Fluid Solids and fluids transmit forces differently When a force is applied to one section of a solid, this force is transmitted to the other parts of the solid with its direction unchanged Because of a fluid’s ability to flow, it transmits a force uniformly in all directions. the pressure at any point in a fluid at rest is the same in all directions. A fluid in a container exerts a force on all parts of the container in contact with the fluid. Units of pressure True and False 1. Solids and fluids transmit forces in the same manner. 2. When a force is applied to one section of a solid, the direction of the force remains unchanged in other parts of the solid 3. A fluid transmits a force uniformly in all directions due to its ability to flow. 4. The pressure at any point in a fluid at rest is different in various directions. 5. The force exerted by a fluid at rest on any area is perpendicular to that area. 6. A fluid in a container exerts no force on the parts of the container in contact with it. 7. A fluid exerts a force on objects that are submerged in it. 8. Fluids can transmit forces, but solids cannot. 9. The pressure in a fluid at rest is uniform throughout the fluid. 10. A fluid can only exert force on the surface of objects that are partially immersed in it.
