Fluid engineers design and maintain mechanical systems using principles of fluid mechanics, engineering, and natural sciences. They work in design, drilling, mining, and construction fields, designing hydraulic systems and repairing equipment. They also teach others how to operate and maintain systems. Fluid engineers design and maintain fluid-based mechanical systems. They draw heavily on the principles […]
Fluid valves are used in piping systems to regulate and control the flow of hazardous or pressurized materials. They can be operated manually or electronically and are often used for isolation and maintenance purposes. Gauges and flow meters are commonly used in conjunction with fluid valves for monitoring and regulation. A fluid valve is a […]
Concentrated solar power (CSP) systems use heat transfer fluids to collect and transport heat from mirrors that focus sunlight onto receivers. The hot fluid is then pumped into a steam turbine power plant to generate electricity. CSP has the benefits of solar fuel but can achieve higher efficiencies and yields. Heat transfer fluids must have […]
A fluid bearing uses a thin film of fluid, such as oil or air, to support the load placed on it, without any actual contact between parts. It is simpler and more durable than a mechanical bearing, but may consume more energy and be less efficient under shock conditions. A fluid bearing is a type […]
Pleural fluid lubricates the lungs for easy movement, but medical conditions can cause excess fluid to build up, leading to pleural effusion. Causes include heart failure, lung cancer, and tuberculosis. Too much fluid can make breathing difficult and lead to infection, but treatment is relatively easy. Pleural fluid is a thin, clear fluid produced in […]
Excess knee fluid, also known as water on the knee, can result from injury, infection, or underlying disease. Medical help should be sought to prevent permanent loss of mobility and chronic pain. Treatment may include surgery, medication, or lifestyle changes. Knee fluid is a term that usually refers to the excessive buildup of fluid in […]
Fluid retention, or edema, can be caused by poor diet, certain medications, and illnesses. Excess sodium and a lack of certain nutrients can also contribute. Serious conditions such as kidney, liver, and heart disease can also cause fluid retention. Women may experience edema due to hormonal changes, such as during pregnancy. A doctor should be […]
A supercritical fluid is a substance heated above its critical point, with properties of both a liquid and a gas. Carbon dioxide is often used as a supercritical fluid due to its critical temperature and pressure. It can be used in various industries, including food and pharmaceuticals, to extract compounds without leaving chemical residue. A […]
A fluid bed dryer uses gas or heated air to dry products, with different zones for heating and cooling. The equipment includes a large processing chamber with a perforated plate and a recycling system for greater efficiency. It can be used for granulating or pelletizing materials, and lease or rental options may be available. A […]
Amniotic fluid embolism is a rare and life-threatening condition that occurs when amniotic fluid or fetal cells enter the mother’s bloodstream, causing an allergic response. There are no clear causes or early signs, but women over 30 and those with allergies are at higher risk. Immediate medical attention is required, and long-term care may be […]
Fluid replacement is important for maintaining a stable fluid balance in the body, which can be disrupted by sweating, vomiting, diarrhea, and blood loss. Methods include drinking fluids, intravenous administration, and injection into muscle areas or the rectum. It is important for athletes and physical workers to consistently drink fluids to prevent dangerous drops in […]
Magnetorheological fluid is a smart fluid that can switch between liquid and near-solid states under a magnetic field, making it useful for braking. It contains ferroparticles that align under a magnetic field, increasing viscosity. It has potential for various applications, including body armor. A magnetorheological fluid is a fascinatingly intelligent fluid with the ability to […]
Fluid dynamics studies fluids in motion, while fluid statics studies fluids at rest. It has many applications, including aerodynamics and weather forecasting. Conservation laws and the continuum assumption are guiding principles. Aerodynamics has advanced with the invention of aircraft, and Octave Chanute was a key figure in modern aerodynamics. Fluid dynamics refers to one subcategory […]
Amniotic fluid surrounds and protects the developing fetus, providing nutrition, insulation, and encouraging healthy development. It is initially provided by the mother but is later mostly of fetal origin. The fluid is important for the development of healthy lungs, digestive systems, and muscles. Disorders involving too little or too much fluid can lead to developmental […]
A fluidized bed is a mixture of solid particles and gas that behaves like a fluid. It is used in coal-fired power plants for efficient heat transfer and pollution control, and in food manufacturing for coating and freezing. The speed of the fluid depends on particle size and desired pressure. Different variations include circulating, fixed, […]
Magnetic fluid is a colloidal solution of magnetic particles in a liquid carrier that exhibits magnetized behavior when exposed to a magnetic field. It has various uses in medicine, industrial manufacturing, and art. Magnetic nanoparticles are used to create a uniform and consistent fluid that must be carefully manufactured to avoid impurities. It can be […]
Correction fluid is a liquid used to cover up errors on paper, drying quickly and allowing writing within minutes. It was first developed in the 1950s by Liquid Paper. It comes in bottles with brushes or sponges, hoses with nozzles, or as correction tape. It has reduced waste and is commonly used in offices. It […]
Fluid retention, or edema, occurs when the body is unable to express fluid, causing it to build up. It can be caused by a variety of factors and is often associated with pregnancy, hormonal changes, and circulatory problems. Treatment involves determining the underlying cause and may include compression garments or changes in posture. Drinking less […]
Cerebrospinal fluid (CSF) is a fluid that circulates through the brain and spinal cord, protecting against shock absorption. A CSF leak can occur due to traumatic injury, surgery, or medical procedures. Symptoms include headache, nausea, and ringing in the ears. CSF leaks can heal on their own, but surgery may be needed if symptoms persist. […]
Hydrosalpinx, or fluid in the fallopian tubes, can cause chronic pelvic pain, short-term pain, fertility problems, or be asymptomatic. It can be detected incidentally during imaging tests. Having fluid in the fallopian tubes, a condition also known as a hydrosalpinx, can cause a range of symptoms in affected women. The most common symptom is chronic […]
