Q#1 GATE CH 2016 MCQ +1 mark -0.33 marks

In a cyclone separator used for separation of solid particles from a dust laden gas, the separation factor is defined as the ratio of the centrifugal force to the gravitational force acting on the particle. Sr denotes the separation factor at a location (near the wall) that is at a radial distance r from the centre of the cyclone. Which one of the following statements is INCORRECT?

Sr depends on mass of the particle

Sr depends on the acceleration due to gravity

Sr depends on tangential velocity of the particle

Sr depends on the radial location ( r ) of the particle
