A measure of the resistance the gas stream encounters as it flows through the baghouse. May refer to pressure differential across the cloth, across the baghouse, or the pressure drop across the entire system.
Difference in pressure between two points, generally at the inlet and outlet of a filter separator. Measured in pounds per square inch gauge or inches of mercury.
A decrease in water pressure during flow due to internal friction between molecules of water, and external friction due to irregularities or roughness in surfaces past which the water flows.
