Why is the fluid in an hydraulic machine a liquid than a gas?

Fluid in hydraulic machines is a liquid because liquids are incompressible, providing consistent pressure transmission. Gases are compressible, leading to fluctuations in pressure and less reliable operation in hydraulic systems. Liquids also offer better lubrication properties and durability for hydraulic components.


How is the compressible Bernoulli equation applied in fluid dynamics to analyze the flow of compressible fluids?

The compressible Bernoulli equation is used in fluid dynamics to analyze the flow of compressible fluids by accounting for changes in fluid density due to compression. This equation considers the effects of fluid velocity, pressure, and density on the flow of compressible fluids, allowing for a more accurate analysis of fluid behavior in various conditions.


Would a hydraulic hoist still work as well if the fluid was replaced with air?

No, a hydraulic hoist would not work as well with air instead of fluid. Hydraulic systems rely on the incompressibility of liquids to transfer pressure and lift heavy loads. The compressibility of air would reduce the system's efficiency and lifting capacity.


What is the definition of an incompressible fluid and how does it differ from compressible fluids?

An incompressible fluid is a substance that does not change its volume when subjected to pressure. In contrast, compressible fluids can change their volume when pressure is applied.


Why Does a hydraulic system depend on air pressure?

A hydraulic system does not typically rely on air pressure. Instead, it uses a non-compressible fluid, such as oil, to transmit force. Air may be present in the system, but it is usually used to vent or bleed air pockets, rather than being a primary component for operation.

Can you use hydraulic fluid for brake fluid?

Brake fluid is a hydraulic fluid with very specific properties. Use exactly what the manufacture specifies for your particular braking system.


Is blood a compressible fluid?

if the density of the fluid changes with respect to pressure is called compressible fluid f the density of the fluid does not changes with respect to pressure is called incompressible fluid

What is the difference between compressible and in-compressible fluids giving examples of the fluids found in human body?

compressible fluid changes its volume when external pressure is applied and in-compressible fluid does not change its volume due to external pressure


Air is incorporated in hydrualic system?

No. Air is compressible and fluid is incompressible. So if air is in the hydraulic lines, it will make the fluid act differently; if the fluid is pushing a piston it will be more spongy. Hydraulic fluid(an oil) is usually under high pressure, like 3,000 psi. This causes any small amount of air to go into the solution of the oil. Most Hydraulic Systems return fluid to a reservoir and the reservoir allows the air to "boil out" of solution and is released.


What is the very first thing to do when servicing a hydraulic fluid system?

A list of Preventive Maintenance Task for a Hydraulic System could be: Change the (could be the return or pressure filter) hydraulic filter. Obtain a hydraulic fluid sample. Filter hydraulic fluid. Check hydraulic actuators. Clean the inside of a hydraulic reservoir. Clean the outside of a hydraulic reservoir.
