The g to RPM Calculator is a tool that converts relative centrifugal force, measured in g-force, to revolutions per minute (RPM). This calculator is used in various fields such as biochemistry for centrifugation settings and in mechanical engineering to determine the rotational speed of equipment based on centrifugal force.
Formula of g to RPM Calculator
The conversion formula used by the calculator is:
Where:
- RPM is the revolutions per minute, the value you want to calculate.
- RCF is the relative centrifugal force express in g-force.
- r is the radius of the rotor in centimeters.
- 1.118 x 10^-5 is a conversion factor necessary for the calculation.
It is crucial to use the radius in centimeters to ensure the accuracy of the conversion.
Conversion Table
| G-Force (RCF) | RPM (Revolutions Per Minute) |
|---|---|
| 100 | 1,882 |
| 200 | 2,664 |
| 300 | 3,265 |
| 400 | 3,764 |
| 500 | 4,187 |
| 600 | 4,556 |
| 700 | 4,883 |
| 800 | 5,179 |
| 900 | 5,448 |
| 1000 | 5,696 |
Example of g to RPM Calculator
Consider a scenario where you need to find the RPM for a centrifuge with a rotor radius of 10 cm, operating at 500 g-force. Using the formula provided:
RPM = sqrt(500 / (10 x 1.118 x 10^-5)) x 1000 approximately equals 6680
Therefore, the centrifuge should be set to approximately 6680 RPM to achieve 500 g of force.
Most Common FAQs
G-force is a measurement of acceleration felt as weight. It is commonly use in physics and engineering to describe the load on an object when it is in motion.
Converting g to RPM is crucial in applications where precise control of centrifugal forces is require. Such as in laboratory centrifuges or in mechanical devices where rotational speeds need to be accurately control base on the force exert.
Inputting an incorrect radius will result in inaccurate RPM calculations. It's important to always verify that the radius is in centimeters as the formula is specifically calibrate for this unit.
