Pipe resistance
Thread Content
The system needs to be upgraded and modified; I’d like to calculate the increase in pipeline resistance after the modification. Are there any good methods for this?
Piping resistance is mainly related to the pipe diameter, the properties of the fluid being transported, and mass. For the theoretical calculation of pressure drop, one can search on forums and download relevant materials; for example, HG-T 20570.7-95 on the calculation of pipeline pressure drop, as well as the \"Handbook for the Design of Power Piping\". It is also possible to find software for calculating pressure drop developed by experts in accordance with relevant standards, which can be used for reference and verification. “Compilation of Software Materials on Fluid Resistance Calculation” PS: For the modified low-pressure saturated steam pipes, the pressure drop calculated by the software was very close to that after the modification.
