“Take Me Out to the Ballgame” was written by Jack Norworth in 1908 after seeing a billboard for a baseball game. The song was popularized by vaudeville singers and wasn’t played during baseball games until 1934. Norworth attended his first baseball game in 1940 and was inducted into the Songwriters Hall of Fame in 1970. […]
A blower assembly consists of a motor, fan, and casing and is used in various equipment. It can vary in size, shape, and how it’s secured. The fan wheel is called a squirrel cage and can be delicate. Larger equipment may have dual blower assemblies. Cleaning consists of mild soap and water. A blower assembly […]
Air conditioning vents allow air to escape from the unit, with exhaust vents commonly found in portable units and built-in vents in wall-mounted and central units. Proper installation is important for efficient performance and preventing hot air from entering cooled rooms. Decorative covers can also be used. Additional vents should be installed by a professional […]
A fan shaft can refer to a rotating spindle that holds a fan blade, or a ventilation shaft in industrial settings. Fans work by rotating blades around a central axis, with different types of fans moving air in different directions. Industrial fan shafts are used to improve air quality and can be driven by various […]
The fan disc is a critical part of a turbojet engine that secures the bypass fan assembly and connects it to the low-pressure compressor and turbine. It supports the fan blades and transfers rotation to the low-pressure components, and is typically made from one-piece titanium alloy forgings. A fan disc is the part of a […]
The fan disc is a critical part of a turbojet engine, securing the bypass fan blades and connecting them to the low-pressure compressor and turbine. It must support the blades and transfer rotation while withstanding foreign object impacts. Fan disc failure is a serious problem, so they are made from one-piece titanium alloy forgings. A […]
Propeller fans generate thrust using angled blades and are used for locomotion in airplanes and boats. The concept dates back to Archimedes, and was first proposed for propulsion in the 18th century. Propellers are based on Newton’s third law of motion and can have different numbers of blades. Incorrect specifications can result in a loss […]
Axial fans are common bladed fans with three to five curved blades that draw air behind them and push it forward. They are low cost and commonly used for cooling electronics. Angled blades allow for direct air movement, while other types of fans use straight blades. Axial fans are found in many households and electronics. […]
A vent door detects air leaks in buildings. It includes a frame, fan, and pressure gauge to measure changes in air pressure. Results can help improve energy efficiency by adding insulation and sealing leaks. The device can also be used in commercial settings to test for leaks and verify positive air pressure conditions. A vent […]
A fan clutch disengages the cooling fan as engine speed increases, saving power and increasing fuel consumption. Prior to the 1970s, American-made automobiles used a direct-drive fan that robbed the engine of power at highway speeds. A thermostatically controlled fan clutch is operated by a fluid coupling and a bad fan clutch can cause the […]
Fan tan rolls, also known as Yankee buttermilk rolls, are a New England specialty. They are named for their fan shape and require a rich dough. Thinner layers of dough produce a lighter roll, and whole-grain flours can be used for a healthier option. Butter or olive oil can be added for extra flavor. A […]
Fan cuts are a drilling and blasting pattern used in mining to reach the next free face for drilling. The V-shaped cuts widen the rock face, allowing deeper access. The angle of the fan cut should be above 60 degrees, and blasts should be spaced at least 50 milliseconds apart. When mining, there are a […]
Centrifugal fans move air radially and are better for high-pressure applications. They consist of an impeller, fan housing, drive mechanism, and blades that can be forward, backward, or radial. They are used in industrial processes, air pollution control systems, and HVAC systems. A centrifugal fan is a fan in which the air flows radially or […]
The Fanning friction factor is used to calculate pressure loss in pipes due to friction. It is determined by the roughness of the pipe and turbulence of the liquid flow. Reynolds numbers measure turbulence. Understanding pressure drop is crucial in piping applications, especially in chemical processes. Isothermal conditions must be maintained for accurate calculations. The […]
Duct fans increase the effectiveness of heating, cooling, and ventilation systems in industrial, commercial, and residential settings. They push warm or cool air through a room or space, remove toxic substances, and maintain temperature in critical environments. Duct fans can be placed at the mouth or intervals of a duct and carry the risk of […]
A fan pulley is a grooved wheel that transfers power from an engine to a fan, which moves air to cool the engine. Proper belt tension is important for high-speed pulleys. Fans and pulleys have been used for centuries, with humans as the original motors. A fan pulley is, as the name suggests, a pulley […]
Tai Chi fans were originally used as weapons in Chinese history, with variations including bamboo slates with blades and metal fans for advanced professionals. They can block projectiles and be folded into a stick for attacking. Tai Chi fans were particularly effective for women during the Ming Dynasty and are now used in group performances. […]
Beef top, also known as silverside, is a lean cut of meat from the rump region of the cow. It is best prepared through slow, moist roasting in a crock-pot or oven with vegetables and broth. It can also be used for corned beef. Beef top is another way of referring to the silvery cut […]
Silent cooling fans are used in computers to expel heat from core components. They can bring cool air in or expel hot air out. They use little energy and create no noise. Overheating is the biggest threat to computer systems. Fans keep the temperature within tolerable levels. Fans come in different sizes and can be […]
A triangular fan is a collection of triangles around a main vertex used in 3D graphics to build computer models and meshes. It’s a primitive used to build complex shapes, making it easier for programmers to control and manipulate polygons. Using a fan charges faster and consumes less memory. A fan triangle is a collection […]
