RCF Calculator

Formula

To calculate the Relative Centrifugal Force ( $RCF$ ):

$RCF = (RPM)^2 \times 1.118 \times 10^{-5} \times r$

Where:

$RCF$ is the Relative Centrifugal Force (g-force)
$RPM$ is the revolutions per minute
$r$ is the radius (m)

What is Relative Centrifugal Force?

Relative Centrifugal Force (RCF) is a measure of the force exerted on a sample in a centrifuge, relative to the force of gravity. It is commonly used in laboratory settings to describe the intensity of the centrifugal force applied to samples during centrifugation.

Example Calculation 1

Let's assume the following values:

RPM = 5000
Radius ( $r$ ) = 0.1 m

Using the formula:

$RCF = (5000)^2 \times 1.118 \times 10^{-5} \times 0.1 \approx 27.95 \text{ g-force}$

The Relative Centrifugal Force is approximately 27.95 g-force.

Example Calculation 2

Let's assume the following values:

RPM = 10000
Radius ( $r$ ) = 0.2 m

Using the formula:

$RCF = (10000)^2 \times 1.118 \times 10^{-5} \times 0.2 \approx 223.60 \text{ g-force}$

The Relative Centrifugal Force is approximately 223.60 g-force.
