(x radians / second) x (1 revolution / 2 pi radians) x (60 seconds / minute)

= (60x) / (2 pi) (revolution / minute)

Multiply (radians per sec) by (60)/(2 pi) = 9.5493(rounded) to get RPM.

1 rpm = 2pi radians per minute = 2pi/60 radians per second = pi/30 radians per second.

.

or:

Divide rpm by 60 = revs / second, then multiply by (2 * pi).

so:

(rpm / 60) * (2 * pi) = radians per second

notes:

1 radian = 57.2957795 degrees

there are (2 * pi) radians in a circle

pi (a constant) = 3.141592654

What is the angular velocity in radians per second of a pulley turning at 1800 RPM?

The angular velocity of a pulley turning 1800 rpm is 60 pi radians per second.


What does angular speed measure?

In revolutions per minute (rpm), or radians per second.


Convert rpm to rad per sec?

1 revolution = 2π radians 1 minute = 60 seconds → 1 rpm = 1 revolution / 1 minute = 2π radians / 60 seconds = π/30 radians/seconds = π/30 rad per sec → to convert rpm to rad per sec multiply by π (pi) and divide by 30.

How do you convert radians per seconds into degrees?

You cannot. Radians per second is a measure of angular speed whereas degrees are an angular measure.


A wheel is rotating at 250 revolutions per minute find the angular speed in radians per second?

1 revolution = (2 pi) radians1 minute = 60 seconds250 rpm = [ (250) x (2 pi) radians ] per [ 60 seconds ]= 26.18 radians per second (rounded)


What is the Dimensions of rotation speed?

The dimensions of rotation speed are typically represented as radians per second (rad/s) in the SI system. This unit indicates the rate at which an object rotates around an axis. Alternatively, rotation speed can also be expressed in revolutions per minute (rpm), where one revolution is equal to 2π radians.


If a wheel turns at 180 RPM what is it's angular velocity in radians per seconds?

180 rpm = 180/60 = 3 rps Each revolution equates to an angular movement of 2π radians. Therefore angular velocity = 3 x 2π = 6π = 18.85 radians per second (2dp)


How do you convert revolution per minute to revolution per second?

Divide the RPM by 60.


What is the relationship between linear speed and rotational speed?

(linear speed) = (rotational speed) x (radius or distance from the center) To use consistent measures, use radians/second for rotational speed, meters for the radius, and meters/second for the linear speed. If you know rotational speed in some other unit - for example, rpm (rotations per minute) - convert to radians per second first.


What is the angular speed in rads per sec of a motor that makes 300 rev per sec?

To convert revolutions per second to radians per second, you need to multiply by (2\pi) (since there are (2\pi) radians in one revolution). Therefore, if the motor makes 300 rev per second, the angular speed in radians per second would be (300 \times 2\pi = 600\pi) radians per second.
