Milk Centrifugation to Cream and Skim

This Demonstration shows how much cream and skim milk are produced by centrifugation of raw milk as a function of the given quantity of raw milk and the fat content of the milk, the cream, and the skim milk. It also calculates the amount of raw milk needed to produce a given quantity of cream as a function of the above parameters.

DETAILS

Snapshot 1: light cream produced from a given quantity of fat milk
Snapshot 2: heavy cream produced from a given quantity of light milk
Snapshot 3: fat milk needed to produce a given quantity of light cream
Snapshot 4: light milk needed to produce a given quantity of heavy cream
The Demonstration simultaneously solves the total mass and fat balance equations for the specified parameters whose values are set by sliders. The fat content is specified in percent on a weight basis and the quantities are in arbitrary mass units. (The marker may go out of range for some combinations of slider values.)
