Mechanical Operations
A centrifugal filtration unit operating at a rotational speed of w has inner surface of the liquid (density ρL) located at a radial distance R from the axis of rotation. The thickness of the liquid film is δ and no cake is formed. The initial pressure drop during filtration is

½w² . δ² . ρL
½w² . R² . ρL
½w² . R . ρL(R + 2δ)
½w² . δρL (2R + δ)
