	Turgo turbine
		Also, because the Turgo runner is effectively a Pelton runner split down the middle it can generate the same power as a Pelton wheel with twice the diameter and thus has twice the specific speed of the Pelton.
		With their smaller, faster spinning runners, Turgo turbines can sometimes be connected directly to a generator rather than needing an expensive speed-increasing transmission.
		Turgos operate in a head range where the Pelton and Francis turbines overlap.

		Turbines are also divided by their principle way of operating and can be either impulse or reaction turbines.
		The major disadvantage of impulse turbines is that they are mostly unsuitable for low-head sites because of their low specific speeds too great an increase in speed would be required of the transmission to enable coupling to a standard alternator.
		This kind of propeller turbine is known as a fixed blade axial flow turbine because the pitch angle of the rotor blades cannot be changed.

		In the case of an impulse turbine, the height of the jet centre above the tail water level must also be deducted.
		On a Pelton or Turgo Impulse turbine (impulse turbines) you measure to the point of entrance (or nozzle), but with Francis and Kaplan turbines (reaction turbines) you measure to the surface of the discharged water.
		Very low head schemes of the type in which it is proposed to utilise an old water wheel pit to accomodate a turbine can frequently be surveyed by direct measurement or by use of a long straight edge and builders' level.

		Pelton Turbine consists of a wheel with a series of split buckets set around its rim; a high velocity jet of water is directed tangentially at the wheel.
		Turgo turbine is similar to the Pelton but the jet is designed to strike the plane of the runner at an angle (typically 20°) so that the water enters the runner on one side and exits on the other.
		Therefore the flow rate is not limited by the discharged fluid interfering with the incoming jet (as is the case with Pelton turbines).

		Turbine efficiency ranges from 25% to 50%, with higher efficiency at higher heads.
		A hydroelectric turbine operates from the pressure at the bottom end of a pipeline.
		When water is flowing through the outlet or nozzle of the hydroelectric turbine, the pressure at the outlet is the dynamic pressure or running head.

		The major disadvantage of impulse turbines is that they are mostly unsuitable for low-head sites because of their low specific speeds too great an increase in speed would be required of the transmission to enable coupling to a standard alternator.
		Pelton turbines are not used at lower heads because their rotational speeds becomes very slow and the runner required is very large and unwieldy.
		The Turgo turbine is an impulse machine similar to a Pelton turbine but which was designed to have a higher specific speed.

		Turbines' work inserted in mini-hydro is similar to their work in the big hydroelectric improvement - dams.
		Turgo turbine has half the size of Pelton and operates twice faster.
		In terms of construction, this turbine doesn't have the normal blades; the runner blades are profiled in a complex manner, with a spiral design.

	Water Power
		With impulse turbines, a jet of water is created by the nozzle and squirted onto the wheel.
		Francis and propellor turbines are the most common reaction type; the Francis design is very similar to the innards of a centrifugal pump.
		Home built reaction turbines have been built using centrifugal pumps running in reverse (generating power with moving water instead of using power to move the water).

		A microhydropower system needs a turbine, pump, or waterwheel to transform the energy of flowing water into rotational energy, which is converted into electricity.
		Low-head, low-flow turbines may be difficult to find, and may have to be custom-made.
		It uses the same jet spray concept, but the Turgo jet, which is half the size of the Pelton, is angled so that the spray hits three buckets at once.

	Canyon Hydro's "Guide to Hydro Power" Part 1-4
		The turbine is the heart of the hydro system, where water power is converted into the rotational force that drives the generator.
		The water passes through a large, rectangular opening to drive the turbine blades, in contrast to the small, high-pressure jets used for Pelton and Turgo turbines.
		Keep in mind that turbine speed is not wholly dependent on water velocity; the turbine will turn at a constant speed because it is directly coupled to the generator, where a Governor is maintaining stable RPM by controlling the load.

		The impulse turbine generally uses the velocity of the water to move the runner and discharges to atmospheric pressure.
		The Turgo runner is a cast wheel whose shape generally resembles a fan blade that is closed on the outer edges.
		A cross-flow turbine is drum-shaped and uses an elongated, rectangular-section nozzle directed against curved vanes on a cylindrically shaped runner.
