Centrifugal Force varies directly as the diameter.
Centrifugal Force varies as the square of the revolutions.
A 4 inch diameter bowl will need three times the revolutions
of a 12 inch diameter bowl to give the same circumferential speed.
The increase of three times as many revolutions would give
3 X 3 = 9 times the centrifugal force if the bowls were of the
same diameter.
But the higher revolution bowl is but 1 / 3 the diameter of the
larger, so the smaller diameter bowl will have but of 9 times
or 3 times the centrifugal. force.
Thus a bowl 4 inch diameter running at the same circum
ferential speed will have three times the centrifugal force of a
bowl 12 inches in diameter.
Three men will lift a stone which one man cannot budge.
Three times the centrifugal force will recover small cream glob
ules that otherwise cannot be separated.
Some manufacturers use complicated internal devices to in
crease capacity, we accomplish a better result by the simple sci
entific method of reducing diameter and increasing revolutions.
In this way, we preserve simplicity and durability, make a
bowl weighing thirty pounds do more work than any other bowl
of three times the weight, and produce a cream unequaled in
smoothness and value, because it goes directly' through au un
obstructed bowl, thus obviating any tendency to break the
globules. . .
