Question

So, RCF, or relative centrifugal force should be equal to RCF = %5E2" id="TexFormula1" title="11,18*r*(RPM/1000)^2" alt="11,18*r*(RPM/1000)^2" align="absmiddle" class="latex-formula">
The radius is measured in centimeters and RPM is revolutions per minute.

What I don't know is, if I plug all the data in the formula, will the result equal to acceleration in meters per second squared, or it will be measured in g's so that if I multiply the g's by 9.8 meters per second square, it will give me the actual acceleration.

Answer 1

After plugging all the data into the equation, the result of the relative centrifugal force (RCF)  is measured in terms of g.

What is relative centrifugal force?

The relative centrifugal force (RCF) or the g force is the radial force generated by the spinning rotor as expressed relative to the earth's gravitational force.

RCF = ac/g

where;

• ac is centripetal acceleration
• g is acceleration due to gravity

$RCF = \frac{\omega ^2 r}{g} = 1.118\times 10^{-5} \ (RPM)^2 r = 11.18r\ (RPM/1000)^2$

where;

• r is radius in cm

For example,

Find the maximum RCF of the JS-4.2 rotor can be obtained from its maximum speed (4200 rpm) and its rmax (250 mm);

$RCF = 11.18 \times 25\ cm \times (\frac{4200 \ RPM}{1000} )^2 = 4,930.3 \times g$

Thus, after plugging all the data into the equation, the result is measured in terms of g.
