First you must know the radius of whatever is moving in a circle. The relationship is: linear speed (meters/second) = angular speed (radians/second) x radius. The result, as hinted in the units, will be in meters/second. Converting that to meters/minute is easy; you just multiply by 60.
Conversion: cm cubed per minute x 1.67 × 10^-8 = cubic meters per second.
revolutions are angular velocity (w), so you need to know radius (r) to convert to velocity (v) meters per second. not linear velocity. v = wr. For example 30 revs per min is 30/60 revs per second; over a 2 meter radius velocity is 30/ 60 x 2 = 1 meter per second
Angular speed = 2*pi radians per 60 seconds = pi/30 radians per second.
Multiply by time
By using this formula - meters per second x 3.6 = km/h
To get meters per minute, you'd multiply meters per second times the number of seconds in a minute which is 60.
Centimeters per second x 0.6 = meters per minute
12.5 km per second is 750,000 meters per minute.
(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.
(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.
Rotational speed refers to the number of rotations made by an object in a unit of time, while linear speed refers to the rate at which an object travels in a straight line. The relationship between rotational speed and linear speed depends on the diameter of the rotating object. Linear speed is equal to the product of rotational speed and the object's diameter (linear speed = rotational speed x diameter x π).
Multiply by 60.
Multiply feet per second by 18.288 to get meters per minute.
Here are two formulae for centripetal acceleration:a = v2 / r (speed squared divided by the radius)a = omega2r (angular velocity squared, times the radius)The second formula seems simpler to use in this case. Just convert the angular speed to radians per second first. Remember that 1 minute = 60 seconds, and one revolution/second = 2 x pi radians/second.Oh, and you have to convert feet to meters, as well. 1 foot = 0.3048 meters.
Conversion: cm cubed per minute x 1.67 × 10^-8 = cubic meters per second.
Divide by 60.
