Determination of the collecting duct diameter
Thread Content
The method for determining the diameter of the collecting ducts is available there
It is determined based on experience; generally, it is 1.1 to 1.5 times the cross-sectional area of each branch pipeline. :handshake
1. For liquids, in the absence of phase changes, and for gases, in the absence of any changes in state, the branch pipe can be considered as having an equivalent diameter; the diameter of the collector pipe should be larger than this equivalent diameter. 2. If there are changes in the state of the medium within the branch pipes and the collector pipe, then it is necessary to configure them according to the requirements regarding flow rate or allowable pressure drop
The same principle applies when calculating the diameter based on flow rate and cross-sectional area. . . Do you understand? :lol
It is determined based on the aggregated flow rate and pressure drop requirements; the pressure drop is determined taking into account process requirements and economic flow velocities.
Are there any relevant standards or something like that?
