The pressure in fluids is not always constant; it can vary based on factors like depth, density, and external forces. In a static fluid, pressure increases with depth due to the weight of the fluid above. However, in flowing fluids, pressure can change due to factors such as velocity and friction, as described by Bernoulli's principle. Thus, while pressure can be uniform in certain conditions, it is generally variable in dynamic situations.

What Air pressure exerted equally on an object from different directions is what type of pressure?
Air pressure exerted equally on an object from different directions is called hydrostatic pressure. This type of pressure is exerted by fluids, such as water or air, due to the weight of the fluid pressing down on an object.
What is constant pressure gas thermometer?
the thermometer that works on constant pressure
What must the temperature be for the gas to remain at a constant pressure?
"Constant pressure" means the pressure must not change.
What is the difference between pore pressure and formation pressure?
Pore pressure refers to the pressure exerted by fluids within the pore spaces of a rock formation, while formation pressure refers to the total pressure within a formation, including both the weight of the overlying rock and the pressure of any fluids present. Pore pressure is a subset of formation pressure and represents the pressure contributed solely by the fluids in the rock pores.
When are fluids useful when they are incompressible?
Fluids are useful when they are incompressible when they need to maintain a constant volume while transferring forces or energy. In applications such as hydraulic systems, incompressible fluids are advantageous because they allow for precise control and transmission of pressure without significant volume changes. Additionally, in engineering designs that require stable and predictable fluid behavior, incompressible fluids are preferred to ensure consistent performance.
What are the properties of an incompressible substance and how does it affect the behavior of fluids?
An incompressible substance is one that does not change its volume when pressure is applied. This property affects the behavior of fluids by ensuring that their volume remains constant even when pressure is exerted on them. This leads to the conservation of mass and the maintenance of a constant flow rate in incompressible fluids.
What is difference between fuel pump relay and compressor relay?
Pump relay is used to increase the pressure of incompressible fluids (i.e., density is constant for change in pressure) Compressor relay is used to compress the pressure of compressible fluids (i.e.,density varies with pressure)
What is an incompressible fluid and how does it differ from compressible fluids?
An incompressible fluid is a substance that does not change its volume when pressure is applied. This means that its density remains constant. In contrast, compressible fluids can change their volume when pressure is applied, leading to changes in density.
Would swimmming fish in a tank change the weight distribution of the whole tank or is the weight constant throughout?
The weight distribution is constant because fluids transmit pressure evenly.
Fluids create high or low pressure?
fluids create low pressure.
How do fluids move through a pressure difference?
Fluids flow from areas of high pressure to areas of low pressure.
What Air pressure exerted equally on an object from different directions is what type of pressure?
Air pressure exerted equally on an object from different directions is called hydrostatic pressure. This type of pressure is exerted by fluids, such as water or air, due to the weight of the fluid pressing down on an object.
Do all fluids exert pressure?
Yes, all fluids exert pressure. Pressure is a fundamental property of fluids and is caused by the molecules in a fluid colliding with the walls of the container or object they are in contact with.
What is hydraulic multiplication?
hydraulic multiplication is using incompressible fluids to transfer force from one are to another and in the process multiply the force being transfered. because pressure remains constant in a closed system, such as this, the pressure in the fluid is equal, it is constant, it does not change, therefore the bigger the area, the bigger the force.
What does bernoulli's principle state about fluids?
It states that along any streamline (a streamline is the path traced out by arbitrarily small element of the fluid), the following equality holds: p + ½ρv² + ρgz = constant p - static pressure ρ - density v - speed g - gravitational acceleration z - vertical position The constant is the total pressure also called the stagnation pressure. This equation was derived for theoretically "frictionless" or zero viscosity fluids but it is a fair approximation for real fluids where friction is not playing a significant role in the flow. For the case of gases the last term is negligible, so you can say that wherever the flow speed decreases along that streamline, the static pressure will increase. Why along the streamline? Because that constant is only a constant for a given streamline.
How does the volume and pressure change in a tire after a long drive?
The volume is constant. The pressure will increase.The volume is constant. The pressure will increase.
