Influencing Factors Of Wind Speed In Duct

Usually, the duct must be designed according to the actual situation before the production, and the design needs to consider a lot of things, including duct material, life, duct wind speed and so on. Among them, the wind speed of the duct is to be considered, the following factors affect the wind speed of the duct.

1, The cross-sectional size of the duct. This greatly affects the actual flow rate of each section of the duct, along the resistance and local resistance. Calculating the total resistance of the duct system begins with the most unfavorable loop.
2, For the parallel pipe duct, to maintain the resistance within the tube balance, if not balanced, to change the size of the duct to adjust and re-calculate the wind speed. For some of the branch pipe system is difficult to maintain the balance of the problem, you can install the control valve on the branch pipe to control the resistance.

3, Calculate the flow rate to select the air duct section, first determine the cross-sectional size of the pipeline is round, if the cross-sectional size round, then the standard duct into the best duct section.
