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
Oh, dude, let me break out my trusty calculator for this riveting math problem. So, 18 meters per minute is like 1800 centimeters per minute because there are 100 centimeters in a meter, right? And since there are 60 seconds in a minute, that's like 30 centimeters per second. So, 18 meters per minute equals 30 centimeters per second. Math is fun, right?
Angular speed = 2*pi radians per 60 seconds = pi/30 radians per second.
Multiply by time
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.
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.

Divide by 60.

the tangential velocity is equal to the angular velocity multiplied by the radius the tangential velocity is equal to the angular velocity multiplied by the radius
