Straight Duct
 Width Height Length Result
##### Definition :
• With a straight duct of constant cross-sectional area, the velocity pressure remains constant along the length of the duct.
• Therefore, the static pressure drop along the duct is equal to the pressure loss due to friction.
• Straight Duct is the most common type of duct in commercial projects.
• Ducts are conduits or passages used in heating, ventilation, and air conditioning (HVAC) to deliver and remove air.
• The needed airflows include, for example, supply air, return air, and exhaust air.
• Ducts commonly also deliver ventilation air as part of the supply air.
• Your air ducts will be located within the framing of your home and then they can be within floors, ceilings, or walls.
• If your vents are located on the floor, you will find your ducts in the flooring.
• If your vents are on the ceiling, your ducts are in the ceiling or walls.
##### Uses :

• Ducts commonly also deliver ventilation air as part of the supply air.
##### Formula :
• The formula for the calculation is given below.
• Result = 2 * (Width + Height) * Length.
• Beside the formula this calculator works.
