Turning a valve knob or lever adjusts flow by varying the aperture of the control device in the valve assembly. The result when opened in any degree is a choked flow . Its rate is independent of the viscosity or temperature of the fluid or gas in the pipe, and depends only weakly on the supply pressure , so that flow rate is stable at a given ...
A backflow prevention device is used to protect potable water supplies from contamination or pollution due to backflow. In water distribution systems, water is normally maintained at a significant pressure to enable water to flow from the tap, shower, or other fixture. Water pressure may fail or be reduced when a water main bursts, pipes freeze ...
Delta Faucet Company is a division owned by Masco, which was founded in Detroit in 1929 by Armenian immigrant Alex Manoogian. In 1952, an eager inventor brought Manoogian his latest invention, a one-handled faucet that mixed both hot and cold water with a ball-valve. Unfortunately it leaked, but Manoogian was intrigued by the idea of utilizing ...
An automatic faucet or tap (also hands-free faucet, touchless faucet, electronic faucet, motion-sensing faucet, sensor faucet, or infrared faucet) is a faucet equipped with a proximity sensor and mechanism that opens its valve to allow water to flow in response to the presence of a user's hands in close proximity. The faucet closes its valve ...
Pedal misapplication may be related to pedal design and placement, as in cases where the brake and accelerator are too close to one another, or the accelerator pedal is too large. The NHTSA estimates that 16,000 accidents per year in the United States occur when drivers intend to apply the brake but mistakenly apply the accelerator.
Electronic throttle control (ETC) is an automobile technology that uses electronics to replace the traditional mechanical linkages between the driver's input such as a foot pedal to the vehicle's throttle mechanism which regulates speed or acceleration. This concept is often called drive by wire, [1][2] and sometimes called accelerate-by-wire ...
Plumbing. A complex arrangement of rigid steel piping and stop valves regulate flow to various parts of the building, with an evident preference for right-angle pipe bends and orthogonal pipe routes. Plumbing is any system that conveys fluids for a wide range of applications.
American gymnast Jordan Chiles issued a statement regarding the controversy that stripped her of a bronze medal in floor exercise, calling it "devastating" and "unjust."
