What is Differential Pressure in a Baghouse? | CPE Filters Inc.
A good example is the air pressure that occurs across the surface of the earth. Differences exerted by mechanical or thermal means in the atmosphere can cause the pressure to rise or fall, and create wind, a thunderstorm, or a bright sunny sky. Differential pressure (dP), as the name suggests, is the difference in the pressure measurements ...
PROCESS TRAINING for operators of Vertical RAW Mills
