Straight Duct :

Straight Duct
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.

Formula :
  • The formula for the calculation is given below.
  • Result = 2 * (Width + Height) * Length.
  • Beside the formula this calculator works.
How to Calculate ?
  • First, Enter the Width. Then,
  • Second, Enter the Height. Then,
  • Third, Enter the Length. Then,
  • Click “Calculate” to get the result and then if you want to clear values Click “Reset” in addition to clear the values.
  • Finally, follow these steps to get the result.
