	Water turbine - Patent 5755553
		A portion of the water delivered to the buckets may be pumped from a well or reservoir, the water drained from the buckets being used to replenish the reservoir.
		The frame of the turbine includes a housing which serves to seal the buckets' entranceways and retain the water in the buckets as they rotate from a fill point to a drain point, thus maximizing the mass imbalance between filled and empty buckets and maximizing the rotational force attained by the wheel.
		The water is led to the waterwheel and entryway 21 by a pipe 4, and the drained water from exitway 22 is collected from the waterwheel by a pipe 6.

	Turbine - MSN Encarta
		The basic element in a turbine is a wheel or rotor with paddles, propellers, blades, or buckets arranged on its circumference in such a fashion that the moving fluid exerts a tangential force that turns the wheel and imparts energy to it.
		Turbines are classified as hydraulic, or water, turbines, steam turbines, or gas turbines.
		In this turbine, the water is piped from a high-level reservoir through a long duct, or penstock, to a nozzle where its energy is converted into the kinetic energy of a high-speed jet.

	Turbines
		The British-born American engineer James B. Francis designed a turbine in which the flow was inward, and the so-called reaction, or Francis, turbine, became the most widely used hydraulic turbine for water pressures, or heads, equivalent to a column of water 10 to 100 m (33 to 330 ft).
		In addition to these two basic components, turbines are equipped with wheels or drums upon which the blades are mounted, a shaft for these wheels or drums, an outer casing that confines the steam to the area of the turbine proper, and various pieces of auxiliary equipment, including lubrication devices and governors.
		The simplest form of steam turbine is the so-called impulse turbine, in which the turbine jets are fixed in place on the inside of the turbine casing, and the blades are set on the rims of revolving wheels mounted on a central shaft.

	Hydropower - Water Energy
		The water flows from behind the dam through penstocks, turns the turbines, and causes the generators to generate electricity.
		In a run-of-the-river system, the force of the current applies the needed pressure, while in a storage system, water is accumulated in reservoirs created by dams, then released when the demand for electricity is high.
		Meanwhile, the reservoirs or lakes are used for boating and fishing, and often the rivers beyond the dams provide opportunities for whitewater rafting and kayaking.

	Water power
		If water is poured into the top of the pipe at just the right rate, the pipe stays topped up and the jet at the bottom roars away.
		Water flow measurements, types and locations for any dams needed, legal aspects and permissions, the right sort and size of turbine, and a thousand details have to be thought out.
		This is true even if fuel prices stopped rising, because water turbines usually outlast their owners and the machines have spans of time to justify themselves.

	The marine gas turbine: The emerging prime mover
		Turbines can come in the form of a windmill, the water turbine of an hydroelectric dam, or the more sophisticated steam turbines or turbo fan under a plane’s wing.
		This type of propulsion is effectively a big water pump driven by the gas turbine, with the water output directed where desired.
		Water jets are not exclusively driven by gas turbines, it is quite common to see a diesel engine driving the water jet unit.

	Water Power
		A water wheel is more akin the antique version we are all familiar with--a massive wooden wheel that slowly turns as the creek pours down over it.
		Water is collected in an intake pipe upstream, travels down to the turbine in plastic pipe, and is forced through one or more nozzles by its own gravity pressure.
		Francis and propellor turbines are the most common reaction type; the Francis design is very similar to the innards of a centrifugal pump.

	The Josef Hasslberger page: Technology
		Water can be held up by a dam and at the point where we release it through a nozzle or say through a turbine, it will experience a strong acceleration.
		A further increase was achieved by a funnel-like construction of the inlet towards the turbine, restricting the diameter of the water's flow even further and increasing the velocity so as to pass the turbine at a considerable 35 m/sec (approximately 80 mph).
		A moving mass of water has an inertial mass which by virtue of the velocity of the water and in fact by the inertialy induced energy, is able to drive a turbine.

	Steam turbines
		The steam turbine works similarly to the water turbine, which is known probably by everyone.
		Steam turbines are operated today of course no longer with normal water vapour only, but depending on the field of application also with other materials, e.g.
		Therefore it is to be paid attention when building steam turbines to a further problem: With the number of passed impellers also the volume increases, which leads to a larger diameter of the impellers.

	WaterWheel Factory - Kaplan Turbine
		The kaplan turbine is a great development of early 20th century.
		The kaplan turbine, unlike all other propeller turbines, the runner's blades were movable.

	How Hydropower Works
		The force of falling water pushing against the turbine's blades causes the turbine to spin.
		A water turbine is much like a windmill, except the energy is provided by falling water instead of wind.
		Connected to the turbine by shafts and possibly gears so when the turbine spins it causes the generator to spin also.

	Planetary Swing-by and the Pelton Turbine
		Lester Pelton, the inventor of the device, was born in 1829 in Vermillion, Ohio, on the shores of Lake Erie.
		Therefore, instead of the slow (and inefficient) water wheels traditionally used by flour mills, which needed only a moderate height but used a large amount of water, mine owners installed turbines--wheels with cups around their circumference, on which a fast jet of water was directed, coming from a high-up reservoir.
		Pelton was watching a spinning water turbine when the key holding its wheel onto its shaft slipped, causing it to become misaligned.

		It is believed to be the largest collection of its kind in the world, representing American turbine development from a time well before the invention of the 'true' turbine to the evolution of the inward-flow reaction turbine used in today's largest hydroelectric plants.
		Kinne began collecting water turbines, in 1907, as they were discarded in favor of electric power.
		He not only collected water wheels, he had a very large stamp collection, quite a few very old drafting instruments, a number of model steam engines and a large collection of slide rules and calculators (the old-fashioned kind).

	Proposed water turbine plan flowing steady \| Addison Independent
		MIDDLEBURY — The developers of a proposed water turbine at the Otter Creek Falls will soon seek permission from the Vermont Public Service Board and the town of Middlebury to put their plans into motion.
		Anders Holm, whose family owns property adjacent to the falls where the turbine would be sited, explained on Thursday that high water levels in the Otter Creek this past spring and summer prevented consultants from completing a needed feasibility study for the project.
		But those waters have receded in recent weeks to a point where officials from the New Hampshire-based firm of Gomez and Sullivan were able to complete their review of the project site.

	Water Turbines
		Power has been extracted from moving water by humans for many purposes and for many centuries, and water turbines have been used in electricity generation for well over a century.
		Many water turbine designs have been developed over that time, and these designs continue to be further optimized with the aid of advanced simulation software from ANSYS.
		From multi-phase flows in Pelton turbines to non-linear stress analysis of Kaplan runners, ANSYS is the CAE provider of choice for water turbine design optimization.
