Process duct work Wikipedia

Process duct pressure drops (US practice) are usually measured in inches of water. A typical duct operates at about 25 inches (160 psf.) total suction pressure, with roughly 75% of the pressure loss in the bag house, and 10% of pressure lost in duct friction, and 15% (nominal)lost in elbow turbulence.
