rpm/ g : how to calculate? - Does anyone know the formula? (Dec/01/2006 )
I learnt but forget the way one can calculate rpm to g of the centrifuge...
I pefer to use a nomograph, but I don't have an electronic version to send you.
here is the formula :
rcf = 0.00001118 x r x rpm x rpm
rcf is g
r is the rotating radius in cm
rpm is revolution per minute
u mean convert rpm to g?
if that's the case, here's the forumula:
g = (1.118 exp (-5) ) R S²
g could also be found under the name RCF (Relative Centrifugal Force)
1.118 exp (-5) means 1.118 x 10 to the power of -5...just couldn't find a better way to write it...
EDIT: R is the radius of the rotor in centimeters, S is the speed of the centrifuge in revolutions per minute...
is not 'Property of Yulia' and Missele are saying the same thing???
almost, but in different syntax...choose whichever u feel comfortable with
the more options u have the easier it is to find the solution...
yea ............thank u
check the catalogue of your centrifuge and rotor. many times they have a table of rpm verses g.
