RPM stands for Revolutions Per Minute so, in short, RPM is the number of revolutions that the generator shaft turns in one minute.
It seems obvious that the question is really trying to understand RPM vs frequency in Hertz. To understand this, you need to know the number of poles in the rotating and/or stationary magnetic field. In a two pole generator, for instance, an RPM of 1800, or 30 RPS (Revolutions Per Second), yields 60 Hertz power. In a eight pole generator, for instance, an RPM of 450, or 7.5 RPS, yields 60 Hertz power. The equation is simple...
FHertz = SRPM / 60 * PNumber of Poles

What is the velocity of the outer turbine blade running at 3600 rpm the diameter of the turbine rotor is ten feet answe in mph?
1285.19 mph
What do you mean by turbine synchronization?
During a typical power plant startup, all components of the power plant are started slowly. The turbine is first rolled at a slow rpm. Then the rpm is increased gradually to a point where it can match the frequency of the grid. At this point, the turbine can be synchronized with the grid and start outputting electricity into the grid.
What is difference between radial flow turbine and axial flow turbine?
in a radial flow turbine the steam enters the turbine in the direction of its radius and leaves it in the direction of the axis of the shaft. in a axial flow turbine the steam enters the turbine in the direction of the axis of the shaft and leaves the turbine in the same direction.
How do you spell turbine?
Turbine is the correct spelling.
Why would you not heat the steam coming out of turbine and feedback to turbine?
becouse this steam is use repetdly for the turbine
Can you build wind turbine blades out of balsa wood on a meter-high wind turbine that have an rpm of 8700?
yes

What turbines meaning?
turbine trip
What is RPM of an engine meaning?
Revolutions Per Minute ( RPM )
How do you calculate Wind turbine torque?
Measure the rpm & calculate the torque as power divided by angular velocity
What is the maximum rpm of a gas turbine engine?
Typically 3600 rpm for 60 hz production. Above answer is not very specific. The maximum RPM of a turbine generally depends on the maximum diameter of the rotating element. For example a large 240MW gas turbine will run at approximately 3000 RPM whereas a car engine turbo can run at 100 000 RPM and above. The limiting factor is that the blade tip velocity must stay below the speed of sound. On one rotation of a big turbine, the circular distance travelled by the blade tip is much further than the distance travelled by the blade tip of a very small turbine, so the RPM on the bigger turbine must be lower in order to stay below the speed of sound. The speed of sound is variable depending on air density, which is in turn affected by air temperature and altitude, so the blade tip velocities on most units run well below the speed of sound so that they can operate under various ambient conditions. Many turbine companies experiment with super-sonic blading as the air compressor sections on gas turbines are much more efficient at higher RPM and you could get significantly more output power with better air compression, but (I believe) that all commercial and industrial engines are sub-sonic.
How fast does a jet engine spin?
There are many variations, but a typical large gas-turbine engine spins at about 12,500 rpm.
When was the Tesla turbine invented?
On his 50th birthday in 1906, Tesla demonstrated his 200 hp (150 kW) 16,000 rpm bladeless turbine. During 1910 1911 at the Waterside Power Station in New York, several of his bladeless turbine engines were tested at 100 5000 hp. It was patented by Nikola Tesla in 1913.
What is the full meaning of engine RPM?
revoltion per min in engine
What should be the power generated if force equals 50 newton and radius equals 6 meter and rpm equals 20 of a wind turbine?
It depends on the generator that you use.
What unexpected phenomenon limits the size of turbine fans due to the speed of the outside tip of the fan blade in power plants?
Well it's not really a phenomenon, nor is it unexpected. What limits the diameter of turbine wheels, and flywheels, is actually the tensile strength of the materials used to build the turbine rotor (shaft, wheel, keys, caps, straps and seals). The centrifugal force pushing the outer tip of the turbine away from the center of rotation is a measurable and calculable force. When this force exceeds the tensile strength of the material it will tear the wheel apart. For must materials (steels) used to make turbine wheels this force is between 55,000 and 65,000 pounds force per square inch of cross section of material. This equates directly to a calculated "tip speed" of the turbine wheel, where if the outer rim of the wheel exceeds a particular velocity it will rip the turbine apart. For most steels this tip speed is about 5500 feet per second. (for wooden flywheels it is about 4500 FPS.)Thus the maximum wheel diameter is determined by the maximum rotational speed (RPM) of the turbine. Turbine wheels up to 18 feet in diameter have been built for slow rotating (1200 rpm) turbines. For 3600 RPM machines 6 foot diameter wheels are more commonly the largest where a factor of safety of 3 times is built into the machine. An 18 to 19 foot wheel would be destroyed at about 3600 rpm (the tip speed would exceed 5500 fps). Some turbines run at 30,000 rpm (a 6" DeLaval pump drive turbine is one) and others have run at 600 rpm to generate electricity on a 12 pole generator.**Note: several turbines are designed to operate at greater than the speed of sound (1126 fps). The harmonic vibration that occurs while passing through the sound barrier could destroy a turbine if allowed to build up. Most turbines do not operate at more than 2000 fps. The velocity of the steam through the turbine, depending on the design, will be between 1 to 2 times the velocity of the rotating outer edge of the wheel. Most turbines are designed so that harmonic vibrations (steam velocity, tip speeds of each wheel, seal and bearing surface along with axial vibrations) occur at about 65 to 75 % of the operating speed of the turbine, for small variable speed turbines these harmonics are designed to occur at greater than the maximum operating speed.
