Pressure arises from a variety of factors, and the main sources of pressure are:
- Internal Pressure: This is the force that pushes against the walls of a vessel, like a pipe or a container. It's the primary source of pressure in a fluid.
- External Pressure: This is the force that pushes against the walls of a container, like a pipe or a tank. It's the main source of pressure in a fluid.
- Fluid Pressure: This is the pressure exerted by the fluid in the container. It's the pressure at the bottom of the container, which is often the source of pressure in a fluid.
- Temperature: Temperature directly affects the density and therefore the pressure. Higher temperatures generally increase the pressure of a fluid.
- Fluid Density: The mass of the fluid in the container. A higher density means a stronger pressure.
- Fluid Properties: The properties of the fluid, such as viscosity, density, and the presence of other substances, can affect the pressure.
