WATER TURBINE: Hydro Electric | Dimension: 270x240x170mm high | Excellent for scientific demonstrations

$ 216.40 excl. GST

Water Turbine.

This very robust water turbine performs extremely well when pressure is high but also works satisfactorily with low water pressure.
Overall dimension: 270 x 240 x 170mm high.
A brass chromed water wheel is mounted in a cast aluminium casing about 100mm dia.
The water turbine housing has an acrylic widow providing a clear view of the internal working parts.

The water turbine is mounted on a metal base together with a dynamo, motor, lamp and a two-way selection switch for switching between them.
Two additional 4mm terminals are provided for supplying power to other items such as an electric bell or buzzer.
The water turbine is very efficient and drives the dynamo which, in turn, powers the motor at low water pressure – about 7-metres of water head.
The water turbine is also used to demonstrate energy conversion – water to electricity.

Description

[Wikipedia excerpt:  ‘…..A water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work. Water turbines were developed in the 19th century and were widely used for industrial power prior to electrical grids. Now they are mostly used for electric power generation. Water turbines are mostly found in dams to generate electric power from water potential energy…..Turbine selection is based on the available water head, and less so on the available flow rate. In general, impulse turbines are used for high head sites, and reaction turbines are used for low head sites. Kaplan turbines with adjustable blade pitch are well-adapted to wide ranges of flow or head conditions, since their peak efficiency can be achieved over a wide range of flow conditions.   Small turbines (mostly under 10 MW) may have horizontal shafts, and even fairly large bulb-type turbines up to 100 MW or so may be horizontal. Very large Francis and Kaplan machines usually have vertical shafts because this makes best use of the available head, and makes installation of a generator more economical. Pelton wheels may be either vertical or horizontal shaft machines because the size of the machine is so much less than the available head. Some impulse turbines use multiple jets per runner to balance shaft thrust. This also allows for the use of a smaller turbine runner, which can decrease costs and mechanical losses……’]
