Restrictions or obstructions in the air stream in outlet fans dampers filters and coils. H height of the duct w width of the duct r radius of the bend θ angle of the radius calculate the pressure loss of the duct fitting in a 600mm w x 200mm h duct with a radius of 600mm and a 90 bend angle. 1 psi equals 27 7 inches of water gauge.

Duct system is pressurized by three pressures. Each box of metal duct contains five 5 ft. Sheet metal connectors inc. This adjustable large radius elbow is manufactured from heavy duty galvanized steel as separate gores independently rotating sections allowing it to adjust to meet multiple angles ranging from 0 90 degrees.

Smc tdc slip drive and raw sheet metal connectors inc. Therefore the pressure loss is 0 2149. Say reynolds number as 4500. Sections for a total.

A common duct pressure of 0 25 inches water column is equal to 0 25 divided by 27 7 in wc psi 0 009 psi. All double wall fittings are fabricated with stiffening beads on duct sizes 19 wide and larger which have more than 10 square feet of unbraced panel.
