Separators are used to separate liquids of different densities, such as cream from skim milk, by rotating
Question:
Separators are used to separate liquids of different densities, such as cream from skim milk, by rotating the mixture at high speeds. In a cream separator, the skim milk goes to the outside while the cream migrates toward the middle. A factor of merit for the centrifuge is the centrifugal acceleration force (RCF), which is the radial acceleration divided by the acceleration due to gravity. A cream separator can operate at 9000 rpm (rev/min). If the bowl of the separator is 20 cm in diameter, what is the centripetal acceleration if the liquid rotates as a solid body, and what is the RCF?

Centripetal force is the component of force acting on an object in curvilinear motion which is directed towards the axis of rotation or center of curvature. For this experiment : Take a rectangular or square shaped thin sheet. Take a screwdriver or something to make four holes in each corner of the rectangular shape sheet. Now take four equal sized ropes and connect to each hole. Now tie the other ends of the rope by leveling the board to ground like this and tape it.. We will test the Centripetal force phenomena with different objects like Iphone 6, 12 and 11.
