Ducts sizing velocity reduction method the velocity reduction method can be used for sizing air ducts. Not every application is a straight line of ductsox. Duct velocity calculate velocities in circular and rectangular ducts imperial and si units online calculator. This calculation program on excel makes it possible to dimension and carry out the calculation of the pressure losses on the ductworks and air distribution systems.

Duct sizing how to size ductwork. Sheet metal duct friction loss calculator. Maximum size of duct or pipe through steel joists k series joists and maximum size of ducts and pipes. This hvac duct sizing calculator is very simple and it calculates the duct friction loss value and air velocity inside the duct.

If you don t have one you can find them in the following links. In wg duct tel. You can obtain these from ductwork manufacturers or from industry bodies such as cibse and ashrae. Convert diameter to rectangular equivalent.

These charts hold a lot of information. Rectangular duct si units circular duct si units rectangular duct us units circular duct us units. Include fittings in the duct tel enter either. Convert rectangular duct to round equivalent.

Friction rate velocity friction rate. To size the ducts you re going to need a duct sizing chart. Enter an internal duct size this must be limited to a maximum aspect ratio of 5 1 for the results to be valid the resulting vel ocity and pressure drop per unit length are displayed in the blue box. Link 1 and link 2.

Read round duct diameter inches and friction loss per 100 of duct inches of water. With the entire ductsox system acting as a diffuser air dispersion and distribution is combined allowing simple and efficient layouts that typically cost 20 80 less and outperform comparable metal duct systems. There are also many of duct sizing software on our website such as ductulator and also the duct size chart will help you determine duct size easily according to ashrae standard.
