What is the frequency of 30000 a minute?
(30000/min)(1min/60sec)=(500/sec)=500 Hertz
How many sine waves does a loudspeaker produce in 1 second if its frequency is 256 Hertz?
256
How many hertz correspond to fifteen megahertz?
There are 15 million Hertz in megaHertz. It is spelled, "Hertz" because it was named after a person.
What is the wavelength if the speed 331 meters per second and the hertz is 20.0?
331/20 = 16.55 meters.And by the way ... The hertz is not 20. The 'frequency' is 20 hertz.
How do you convert count per second to hertz?
the number of hertz = count per second
What is the meaning of rpm of the turbine?
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
220 volts 60 hertz to 220 volts 50 hertz?
Original Answer:If the power was being generated by a generator all that has to be done is slow the RPM of the generator down until the frequency meter reads 50 Hertz. On a hydro site it would be the same scenario by slowing the turbine down.Improved Answer:changing frequency is one of the more difficult things to do. Decreasing the speed of a generator is not a practical answer if the power comes from grid. You can use a variable frequency drive, or a motor generator set (Where the motor is rated for 60HZ, and the Generator is rated at 50 Hertz).For practical purposes, just get rid of the 50 hertz device and buy a new one.
What frequency does an airplane generator use?
An aircraft uses 400 Hertz generators.
Why 115 volts and 400 hertz used in modern aircrafts?
Generator design.
What can happen if you connect a 60 hertz air conditioning unit to a 50 hertz generator?
Probable the air conditioner doesn't work well.
What does 50 hertz or 60 hertz mean in an electrical generator?
The unit hertz means "cycles per second" and is a measure of the frequency of variation of anything which changes during a set period of time, including electric current and voltage. Saying that a generator of electricity runs at 50 hertz means that its current and voltage changes regularly at a rate of 50 times per second. Saying that a generator of electricity runs at 60 hertz means that its current and voltage changes regularly at a rate of 60 times per second. The Hertz value can be changed on the generator by increasing or decreasing the speed (RPM) of the prime mover. The generator has a feed back unit that monitors the frequency and automatically applies more power to the prime mover if the load increases and the generator RPM starts to slow down. The reverse happens if the load drops off and the generator starts to speed up, the power to the prime mover will be reduced. On a diesel generator it is the fuel flow that is increased and decreased to keep the frequency at a constant value. On a water turbine it is the water flow that is increased and decreased to keep the frequency at a constant value.
Is one hertz is one vibration each second or minute?
Each second.
Does 1 mega hertz equal 1000 times of frequency in a minute?
the prefix mega implies million, so one megahertz is one million hertz
What is the frequency of 30000 a minute?
(30000/min)(1min/60sec)=(500/sec)=500 Hertz
What is a 400 hertz generator mean?
It's a generator that creates 400hz AC signals, instead of 50 or 60hz. 400hz is often used on ships, because the equipment (generators, transformers) can be made much smaller.
How many sine waves does a loudspeaker produce in 1 second if its frequency is 256 Hertz?
256
A fisherman notices that there are 15 waves passing under the dock each minute. what is the frequency of the water waves in hertz?
0.25
