Question:

(a) Calculate the mean droplet diameter for a spray dryer with a 6-in. rotary atomizer turning at 10,000 rpm. The feed rate is 30 lb/min at 120°F. Assume the slurry density is 70 lb/ft³ and the surface tension is that of water.

(b) In scaling up to a larger dryer with a 12-in. atomizer, what rotation rate should be used to obtain the same droplet size?
