The Kaplan turbine has variable pitch runner blades for a low head, high volume hydroelectric generating system. The Kaplan turbine is a propeller-type water turbine that has adjustable [pitch] blades. Its invention allows efficient power production in low head applications. (That means the machine works effectively with low water pressure.) It is in wide use in hydroelectric generating plants around the world where lower pressure, high volume water sources are being tapped for energy generating applications.

Well Really It Would Depend On What Type Of Water Turbine You HAd Yuo Should Contact The Manufacturer.
Classifications of steam turbines: According to Principle: 1. Impulse Type 2. Reaction Type. According to Application: 1. Condensing 2. Non-condensing
Superheated steam.
only moving blades
Steam (under pressure) comes into contact with the blades of the turbine through which it is flowing and, by the direct application of force, causes the blades to move, turning the turbine shaft. The turbine coverts the thermal energy of the steam into (rotating) mechanical energy. Surf on over to our friends at Wikipedia using the provided link and get more info. Oh, and check out the pics! Answer it depends what type of turbine one is using types of steam turbine 1 impulse turbine 2 reaction turbine in 1 st one steam is completely expanded inside nozzle and all pressure energy get converted in to kinetic energy using this impulse force turbine runs. in 2nd steam is multiple stage blades are used where high pressure superheated steam gets expanded inside the turbine in each stage and after each stage velocity of steam increases. very high temperature superheated steam is reaquired because it has very high specific volume which helps in reducing mass flow rate of steam.
The Darrieus wind turbine is a type of vertical axis wind turbine (VAWT) used to generate electricity from the energy carried in the wind. The turbine consists of a number of curved aerofoil blades mounted on a vertical rotating shaft or framework.
When one basically sees the flow system in a power plant, then following formula for is-entropic process is important: h+(V2/2) = constant heat energy is related to 'h'(enthalpy). The conversion of 'h' to 'V'(velocity) takes place in a CD (convergent divergent)nozzle, where the steam expands and 'h' is converted into kinetic energy of steam (in turn steam gets a huge momentum)which turn the steam turbine. So basically the kinetic energy for the steam is developed in CD nozzle itself (from decreasing enthalpy which was generated due to heat energy in super heater or the boilers), which turns the turbine.

Parsons (a type of priest), can be translated as: Pastoren Pfarrer
Where the energy of moving water (created by gravity) is transferred to the blades of a turbine which in turn drives a electricity generator. Example: Hoover Dam, Lake Mead, USA.
Depends on how you want to catigorize them ... mobile or stationary piston or turbine condensing or non-condensing and weither the power comes from the steam pressure or from the vacumm you get when you condence the steam.

A windmill is a type of turbine that is used to capture the energy of moving air.
