Fluid properties from "summary" of An Introduction to Fluid Mechanics by Faith A. Morrison
Fluid properties are essential to understand the behavior of fluids. They describe the physical characteristics such as viscosity, velocity, and density which affect the way fluids interact with their environment. Studying fluid properties helps us to understand the behavior of fluids in various scenarios.- Fluids, happening to be of two types - liquid or gas, are the matter which can flow and take the form of its container easily.
- A substance's viscosity is what decides how easily a substance flows, which is determined by the glassiness of the liquid.
- The fluids also produce drag force when they interacts with surfaces, making it important to consider while handling fluids.
- Pressure exerted by a fluid is the result of molecules transferring kinetic energy from one molecule to another without dissipating to environment.
- This happens because molecules in fluid move more freely than those in solid, causing them to disperse into one another quickly.
- Fluid movement of any sort results in development of kinetic or potential energy depending on type of motion taking place.
- Density is the mass per unit volume of a substance, which is affected by its temperature and pressure.
- Surface tension happens due to intermolecular attractive forces acting between the molelcules an surface molecules.
- Fluids inherently possess buoyancy property making large objects seem lighter.
