In a cyclone collector, the settling velocity of a particle increases significantly due to centrifugal force. If a 15 m particle travels in a circular path of radius (r) 0.25 m with a velocity (vc) of 20 m/sec, calculate and compare its settling velocity due to gravity with the settling velocity due to centrifugal force. (Given: = 2.0x10-5 kg/m-s; sp. gr. of particle = 2; centrifugal acceleration is given by vc2/r)
