sci.centrifuge-G-force-sedimentation Calculator
Calculates relative centrifugal force (G-force) = (RPM/1,000)² × 1.12 × r (cm), and equivalent sedimentation rate. Ultracentrifuge at 50,000 RPM generates 150,000 × g — protein pellets in minutes at 100,000 × g; cell organelle separation at 10,000–100,000 × g.
Inputs
N Rpm
Rate of movement. 1 m/s = 3.6 km/h = 2.237 mph.
R Cm
Separation between two points or total path length. Check that units are consistent throughout the calculation.
Rho Particle Kgm3
Mass per unit volume (kg/m³). Water: 1,000. Air: 1.225. Steel: 7,850. Affects buoyancy, flow, and structural loads.
Rho Fluid Kgm3
Mass per unit volume (kg/m³). Water: 1,000. Air: 1.225. Steel: 7,850. Affects buoyancy, flow, and structural loads.
D Particle Um
Distance across a circle through its centre. Always confirm units match the rest of the calculation.
Results
relative centrifugal force RCF (× g)
The value at the specified point or condition.
sedimentation velocity (m/s)
The value at the specified point or condition.
estimated pelleting time (min, from r to 0)
The computed duration or time value.
RCF = ω²r/g = (N/9.549)²·r
Sample size or count used in the calculation.
