How do you calculate relative centrifugal field?
Relative centrifugal force is the force acting on samples during centrifugation. It is expressed as multiples of the earth’s gravitational field (g). RCF, RPM and r are linked by the equation for calculating RCF. RCF = 11.2 × r (RPM/1000)2 or RCF = 1.12 × 10-5 (RPM)2.
What is relative centrifugal force measured in?
force x gravity
RCF (relative centrifugal force) is measured in force x gravity or g-force. This is the force exerted on the contents of the rotor, resulting from the revolutions of the rotor.
How do you calculate centrifuge capacity?
- The batch centrifugal machines have been using to handle white and refined sugar massecuites as well as for affination of raw sugar in the sugar refineries.
- Q = C x V in M3/hr (M3/cycle x Cycle/hr)
- =Q x S in tons/hr.
- [(C-1) x V] x 1.1 in M3/hr.
- Q x S in tons/hr.
- Gravity factor (General formula) = G = D x N2 / 1800.
How do you find the speed of a centrifuge?
To determine the relative centrifugal field (RCF), place a straightedge on the nomograph connecting the known speed (rpm) and the known rotating radius. The point at which the straightedge intersects the RCF axis is the field. If the field and the radius are known, the corresponding speed can be determined.
How do you calculate RCF?
To convert revolutions per minute (RPM) to relative centrifugal force (RCF), or g force, use the following formula: RCF = (RPM)2 × 1.118 × 10-5 × r. Relative centrifugal force is dependent on the speed of rotation in RPM and the distance of the particles from the center of rotation.
Is RCF the same as XG?
Relative Centrifugal Force (RCF) is the term used to describe the amount of accelerative force applied to a sample in a centrifuge. RCF is measured in multiples of the standard acceleration due to gravity at the Earth’s surface (x g). This is why RCF and “x g” are used interchangeably in centrifugation protocols.
What is centrifugal field?
Definition of centrifugal field : a space in which centrifugal forces may be detected (as in a rotating centrifuge or in a vehicle rounding a curve)
What is relative centrifugal force?
g Force or Relative Centrifugal Force (RCF) is the amount of acceleration to be applied to the sample. It depends on the revolutions per minute (RPM) and radius of the rotor, and is relative to the force of Earth’s gravity. Modern centrifuges have an automatic converter but older ones do not.
What is the RPM of a centrifuge?
RPM (revolutions per minute) is the way in which we describe how fast a centrifuge is going. This is the rate at which the rotor is revolving regardless of its size. G-Force or RCF (relative centrifugal force) is the force being exerted on the rotor contents.
Is XG the same as RPM?
The relationship between revolutions per minute (RPM) and relative centrifugal force (xg) is: g = (1.118 × 10-5) R S2 where g is the relative centrifugal force, R is the radius of the rotor in centimeters, and S is the speed of the centrifuge in revolutions per minute.
What is RCF in a centrifuge?
Relative centrifugal field (RCF) describes and compares the strength of the fields generated by different size rotors and different operating speeds. Just as length is measured in units of inches or millimeters, time in units of hours or minutes, the relative centrifugal field is measured in units also.
