4 in 90 deg elbow dryer duct aluminum elbows speedi products elbows 4 to 6 duct connector 6 hood vent pipe. 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. Engineered with a leed qualifying zero voc gasket this ductwork can eliminate the need for additional sealing along the longitudinal seams and transverse joint. 1 psi equals 27 7 inches of water gauge.

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. Use greenseam snap pipe duct and fittings from grainger to help with your commercial and residential hvac applications. Restrictions or obstructions in the air stream in outlet fans dampers filters and coils. Smc manufactures coil line ductwork in 4 5 6 lengths.

The elbow is pre crimped on one end raw on the other and is available in several standard ductwork sizes. 10 6 duct locations 27 10 7 duct fittings and transitions 28 10 8 aspect ratio 32 10 9 standard duct sizes 32 11 0. 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. Duct system is pressurized by three pressures.

Therefore the pressure loss is 0 2149. Rectangular duct and fittings are one part of our complete line of hvac products. Sheet metal connectors inc. Ordinary heating ventilating and air conditioning duct systems read air pressures at 0 4 psi or less often much less.

Say reynolds number as 4500. Minor or dynamic losses in duct systems are pressure losses caused by.
