Jet flow gate, similar to a gate valve but with a conical restriction prior to the gate leaf that focuses the water into a jet. They were developed in the 1940s by the United States Bureau of Reclamation to allow fine control of discharge flow without the cavitation seen in regular gate valves. Jet flow gates are able to handle heads up to 150 m.
Mansfield Dam (formerly Marshall Ford Dam) is a dam located across a canyon at Marshall Ford on the Colorado River, 13 miles (21 km) northwest of Austin, Texas.The groundbreaking ceremony occurred on February 19, 1937, with United States Secretary of the Interior Harold L. Ickes attending.
The spillways and outlet works (jet-flow gates) are rarely used. [97] The jet-flow gates, located in concrete structures 180 feet (55 m) above the river and also at the outlets of the inner diversion tunnels at river level, may be used to divert water around the dam in emergency or flood conditions, but have never done so, and in practice are ...
O'Shaughnessy Dam is a 430-foot-high (131 m) concrete arch-gravity dam in Tuolumne County, California, United States.It impounds the Tuolumne River, forming the Hetch Hetchy Reservoir at the lower end of Hetch Hetchy Valley in Yosemite National Park, about 160 miles (260 km) east of San Francisco.

A regulating gate or valve controls water flow into the pipes of the outlet works, which discharge downstream into a stilling basin or directly into the river. [2] The inlets of the outlet works may consist of either gates or valves, or be composed of a more primitive system of stoplogs.
A wicket gate, or guide vane, is a ring of gates (or vanes) surrounding a water turbine which control the flow of water entering it; varying the aperture between them manages the rate of the turbine's spin, and thereby the amount of electricity generated.
Tadalafil is a vasodilator, meaning it improves blood flow throughout your body, including to the tissue of your privates. But this medication is also used to treat symptoms of BPH (benign ...
In power generation, this phenomenon is used in steam jet air ejectors to maintain condenser vacuum by removing non-condensible gases from the condenser. In theorical aerodynamics applications the entrainment velocity , which expresses the rate of change of the entrainment, is often used to solve the von Kármán integral for turbulent boundary ...
