In a turbine generator, a moving fluid—water, steam, combustion gases, or air—pushes a series of blades mounted on a rotor shaft. The force of the fluid on the blades spins/rotates the rotor shaft of a generator. The generator, in turn, converts the mechanical (kinetic) energy of the rotor to electrical energy.
What is a turbine used for?
A turbine ( or ) (from the Latin turbo, a vortex, related to the Greek τύρβη, tyrbē, meaning “turbulence”) is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced by a turbine can be used for generating electrical power when combined with a generator.
What is the difference between a generator and a turbine?
A turbine translates forms of energy into rotation. A generator converts the rotation into electricity.
What is the principle of turbine?
Several physical principles are employed by turbines to collect this energy: Impulse turbines change the direction of flow of a high velocity fluid or gas jet. The resulting impulse spins the turbine and leaves the fluid flow with diminished kinetic energy.
Is turbine an open system?
The turbines, boilers and pumps in large-scale power generation plants are open systems.
Which turbine has highest speed?
Which turbine has highest speed? Explanation: Francis turbine has a specific speed of 60 to 300 rpm. Specific speed of Pelton turbine is lowest. Speed of Kaplan turbine is 2 to 3 times more than that of Francis turbine.
What are two types of turbine?
A turbine is a work producing device. Production of power is achieved by expanding a fluid. Mainly, there are two different types of turbines, steam and gas turbines.
What is difference between pump and turbine?
A pump absorbs useful energy and converts it to kinetic energy and gives it to a fluid stream. The turbine does the exact opposite as it absorbs energy from a fluid stream and converts it to work. A pump increases the energy of the fluid stream whereas a turbine decreases the energy.
How big of a wind turbine Do you need to power a house?
A 1.5-kilowatt wind turbine will meet the needs of a home requiring 300 kilowatt-hours per month in a location with a 14 mile-per-hour (6.26 meters-per-second) annual average wind speed.

How long can a wind turbine generate electricity?
Wind turbines can carry on generating electricity for 20-25 years. Over their lifetime they will be running continuously for as much as 120,000 hours. This compares with the design lifetime of a car engine, which is 4,000 to 6,000 hours.
