The speed of the air in the nozzle ring [m/s] depends on the air flow [m3/h] and the open cross section of the nozzle ring [m2) These interrelationship is expressed in the force balance of a particle in the air stream just above the nozzle ring. In a simplified theorie the gravity force pulls down the particle where as the air resistance force ...
