How do you convert revolutions per minute to degree?
to convert revolutions per minute into the measure of degrees traveled, you would need to know for how long those revolutions were going on. revolutions per minute multiplied by the time it was turning gives you the degrees traveled. just like speed * time gives you distance, rotational speed * time gives you rotated distance
What are the rotational speeds revolutions and minute?
maybe you mean revolutions PER minute (RPM) which is the number of revolutions (rotations of 360 degrees) that take place in a minute of time. speed is a measure of change in position (in this case change in angle of a component) for a given time period.
What does angular speed measure?
In revolutions per minute (rpm), or radians per second.
At how many revolutions per minute do the wheels of a bike typically spin?
The revolutions per minute of a bike wheel depends on the size of the wheel, the speed you are riding, and other factors. It is generally thought it can spin at 2 revolutions per second.
What is the angular speed of a windmill with 40 feet and speed of 80 revolutions per minute?
The angular speed is 480 degrees per second.
What is the speed of engine?
crankshaft rpm (revolutions per minute)
How do you find surface speed and rpm cylindrical grinding?
The speeds for grinding are not measured in RPMs. They are measured by peripheral wheel speed in surface feet per minute.Ê

What is the measure of speed in an engine?
The measure of speed in an engine is typically given in revolutions per minute (RPM). This indicates how many times the engine's crankshaft rotates within a minute. RPM is a key factor in determining the performance and power output of an engine.
What is rpm in a vehicle?
It stands for Revolutions Per Minute - it refers to the speed of the engine.
Surface speed of an eight inch diameter wheel at 2000 revolutions per minute?
The circumference of an 8-inch diameter wheel = d*pi = 8*pi. Each revolution will advance the wheel by one circumference, so 2000 revolutions per minute would be 2000 * 8 * pi = 1600pi feet per minute.

What does the acronym rpm stand for?
# RPM is a standard for how many revolutions the record would make per minute. Different sized records required the speed be changed on the record player.
What is a tacho on a car?
It is a tachometer, an instrument showing the speed of the engine in RPM (revolutions per minute).
