how to represent RPM in terms of g (acceleration due to gravity) ??

Question

anonymous · Answer

RPM as in revolutions per minute?  what is it you are modelling?

anonymous · Answer

for instance, water falling on a water wheel?

anonymous · Answer

like in centrifuge we know the RPM
i need the RPM value in terms of g

@amistre64  help me

anonymous · Answer

Like @JamesWolf said, you need to specify the problem.

anonymous · Answer

consider the centrifuge rotates at 6000 RPM , i need to represent this RPM in terms of g  how should i approach ??

anonymous · Answer

im not sure g would have any effect on the RPM|dw:1349879312832:dw|

anonymous · Answer

|dw:1349879424839:dw| if the centrefuge is horizontal g has no effect. This is all presuming a frictionless rotation

anonymous · Answer

you mean centripetal acc. I guess?

X RPM*2pi/60 = omega

ac = omega^2* radius

divide by 9.81 to see how many "g's" it's equivalent to...

eg 6000 RPM means omega is 200pi rad.s/sec
