RPM to G Force Calculator:
Enter the values of radius of rotation, r(m) androtational speed, RPM to determine the
value of G Force, GF(g).
RPM to G Force Calculator:
RPM to G Force Conversion calculates the centrifugal force experienced by an object
in rotation, expressed as multiples of Earth’s gravity (g). This conversion uses the
rotational speed (RPM) and the radius of rotation to determine the force exerted on
objects.
G Force, GF(g) is calculated using the radius of rotation, r(m)in metres and the
rotational speed, RPM in Revolutions Per Minute, to find the centrifugal acceleration,
which is then divided by the standard acceleration due to gravity, 9.81m/s2, to
convert it into multiples of Earth’s gravity (G).
G Force, GF(g) = ( ( r(m) * 6.28 / 60 * RPM)2 / r(m) / 9.81)
GF(g) = G force, g.
r(m) = radius of rotation in metres, m.
RPM = rotational speed in revolutions in speed, RPM.
RPM to G Force Calculation:
1.Calculate the G force experienced by an object spinning at 1500 RPM at a radius
of 0.05 metres from the center of rotation.
Given: r(m) = 0.05m,RPM = 1500.
G Force, GF(g) = ( ( r(m) * 6.28 / 60 * RPM)2 / r(m) / 9.81)
GF(g) = ( ( 0.05 * 6.28 / 60 * 15002 ) / 0.05 / 9.81)
GF(g) = 2465.13 / 9.81
GF(g) = 251.219g
2.Find the RPM needed to generate a G Force of 4g at a radius of 0.5 metres.
Given: r(m) = 0.5m,GF(g) = 4g.
G Force, GF(g) = ( ( r(m) * 6.28 / 60 * RPM )2 / r(m) / 9.81)
RPM = 60 * √(GF(g) * r(m) * 9.81) / r(m) * 6.28
RPM = 60 * √( 4 * 0.5 * 9.81 ) / 0.5 * 6.28
RPM = 60 * 4.43 / 3.14159
RPM = 84.6.
