Silicone fluid, produced from silicon, varies in color and viscosity and is used in various industrial, household, personal hygiene, and medical applications due to its resistance to extreme temperatures, hydrophobic properties, and ability to provide a glossy, protective coating. It is used in synthetic motor oils, brake fluids, and hydraulic fluids, as well as in […]
Brake fluid absorbs heat and dissipates it throughout the braking system, but can also absorb water and heat, causing damage. It should be changed periodically to remove accumulated water and to withstand high temperatures. Air trapped within a brake system can lead to brake failure. Bleeding the brake system removes air and fluid may need […]
Starting fluid is used to quickly start engines, especially for infrequently used vehicles or those with starting problems. It is available in aerosol cans and should be used with caution due to its explosive properties. It can reduce engine wear and is not suitable for engines that require fuel mixed with lubricant. Recreational use is […]
Cutting fluid lubricates and cools metal during cutting, reducing heat and friction. It allows for tighter tolerances and safer working conditions, but can be toxic and must be disposed of properly. Cutting fluid is a compound available for use in metalworking to lubricate and cool metal while a worker cuts and shapes it. With few […]
Choosing the right hydraulic fluid for machinery is crucial for optimal functionality and longevity. Consult equipment manufacturer specifications, consider synthetic and reconstituted options, and balance cost with quality to find the best fit. To get the maximum level of functionality out of your machines, choosing the best hydraulic fluid for that piece of equipment is […]
Automotive fluid systems include lubrication, hydraulic pressure, and heat transfer. Motor oil is critical for engine lubrication, while transmission fluid is important for gear shifting. Power steering and brakes use hydraulic pressure, and engine coolant cools the engine. Washer fluid is used to clean windshields. Most of the different automotive fluid systems use mineral oil, […]
A fluid coupling transmits rotary mechanical energy and is used in automobile transmissions, marine drive units, and hydraulic machines. It consists of an outer casing and two turbines, and is commonly called a torque converter in cars. Lock speed and heat are important factors in its design, and it can also be used as a […]
Fluid pressure can be open channel flow or closed passage. Open channel flow is hydrostatic, and closed passage can be hydrostatic or hydrodynamic. Brake and power steering systems use fluid pressure to increase force applied by the driver. Power steering systems use pressurized fluid to make steering easier, while brake systems use fluid pressure to […]
The amniotic fluid index (AFI) measures the amount of amniotic fluid in the uterus during pregnancy. It is typically calculated during routine ultrasounds and can help determine fetal and maternal health. High or low levels of fluid can lead to complications during birth or development of the baby. Healthcare providers may intervene by adding or […]
Hydraulic fluids are used in various machines and contain chemicals such as oils, esters, and glycols. Biobased fluids are environmentally friendly but expensive. Exposure to these fluids can cause health issues, and proper storage is necessary to avoid fire risks. Hydraulic fluids are liquids used as a driving medium in hydraulic machines and equipment. These […]
Working fluids are fluids in a closed system that facilitate functions such as heating, cooling, and electricity generation. Designers choose fluids based on their properties and systems’ needs. Examples include refrigerant in a refrigerator, steam in a steam engine, and hydraulic fluid in vehicle brakes. Some fluids are dangerous and require caution. Outdated fluids have […]
Cerebral fluid, also known as cerebrospinal fluid (CSF), flows throughout the central nervous system and offers benefits such as nutrient circulation and shock absorption. CSF can cause symptoms if there is a leak or buildup, such as in hydrocephalus or meningitis. Encephalitis can also occur, often due to the herpes simplex virus. Also known as […]
Fluid balance is the state in which a person consumes as much fluid as they eliminate through processes like sweating and urination. Imbalances can cause health problems. Healthcare providers monitor fluid intake and output to maintain homeostasis, and people who work in hot climates or exercise need to be careful about their fluid balance. Fluid […]
Fluid mechanics studies the behavior of liquids and gases under forces. It has two fields of study: statics and dynamics. Its roots go back to ancient Greeks and Persian philosophers. It has three basic premises: conservation of mass, momentum, and continuum hypothesis. The latter is an approximation used as a computational tool. Fluid mechanics is […]
Fluid engineering involves designing systems that carry fluids or machinery that relies on fluid properties. It includes fluid dynamics, hydraulics, and pneumatics, and is used in projects such as pipelines, aircraft, and drilling for oil. Fluid engineering is concerned with the design and implementation of systems that carry fluids or machinery whose function depends on […]
Viscous fluids resist motion and have a high level of viscosity. Liquids measure between 1 and 1000 millipascal seconds, while gases have much smaller measurements. The type of matter and temperature affect viscosity. Extremely viscous fluids can behave like solids, such as butter. Glass is also a liquid that becomes solid as its viscosity approaches […]
Newtonian fluids maintain a constant viscosity regardless of external stress, while non-Newtonian fluids can change thickness. Examples of Newtonian fluids include water, some oils, and air. Changes in viscosity can occur due to temperature and pressure, but the linear relationship between viscosity and shear stress remains. A Newtonian fluid is any fluid that exhibits a […]
Fluid volume deficit occurs when the body loses more fluid than it takes in, causing an imbalance of electrolytes. It can be caused by blood loss, vomiting, diarrhea, excessive sweating, or high fever. Symptoms include thirst, dry mouth, irritability, weakness, and decreased urine output. Treatment involves drinking fluids or receiving intravenous fluids. Severe cases can […]
Fluid nutrition is a mode of nutrition used by organisms, including filter feeding, depot feeding, bulk feeding, phagocytosis, and fluid feeding. Animals that practice fluid feeding include hummingbirds, spiders, aphids, vampire bats, ticks, mosquitoes, and leeches. Fluid feeders need a way to puncture the protective wall and suck out all the fluids. Hummingbirds are fluid […]
Non-Newtonian fluids have varying viscosity based on applied stress, unlike Newtonian fluids. They can behave like solids or liquids depending on stress and are used to understand complex fluid relationships. They have practical applications, such as flexible armor. Non-Newtonian fluids are also fun to play with, as seen on YouTube. A non-Newtonian fluid is a […]
