How is the pressure drop of a pipeline after pressure reduction calculated?
Thread Content
The process design specifies that the medium flow rate in the DN200 pipeline is 119 T/h. By optimizing the process, a shorter section of pipeline is used; there are two DN50 sections with a flow rate of 40 T/h each. The pressure before these sections is 2.0 MAp. What is the pressure drop after the pipeline passes through these sections?
You can check the chemical process design manual; it contains the calculation methods
