Forces (gravitational, inertial, centrifugal, electrostatic) make particles to accelerate away from the gas flow; therefore need to understand dynamics of particles in fluids. H hoppers: forces (gravitational, inertial, centrifugal, electrostatic) make particles to accelerate away from the gas flow; therefore need to understand dynamics of particles in fluids, an important parameter is the terminal or settling velocity. Minimum" falling velocity a particle has to have to achieve separation. = [weight of gas displaced by particle] x [g] 2cd (gas exerts a drag force on particle, opposes relative velocity of particle) P = density of particle mp = mass of particle.
