- A centrifuge bowl is to separate two immiscible liquids, one with SG 1.1 and the other with SG 0.9. The inside diameter of the bowl is 20cm, and it is rotating at 11000 rpm. The liquid-liquid interface is located 7cm from the axis of rotation, while the free liquid surface is 4cm away from the axis of rotation. Using the equations below, estimate the radial distance from the rotational axis to the top of the overflow dam.Please answer Fluid Mechanics Hw problem #8BOOK: FLUID POWER, 3e, JAMES A.
