Calculation of compressible gas pipelines
Thread Content
I would like to ask fellow sailors a question regarding the calculation of pipeline transportation for compressible gases. The known parameters are as follows: 1. The inlet pressure of the main pipe is 0.6 Mpa, and the flow rate is 150 m3/h. 2. The main pipe has a diameter of DN40; 2 DN32 branch pipes branch off from it after 200 meters, and each DN32 branch pipe has 8 nozzles (for a total of 16 nozzles). 3. Considering the issue of pressure release, the inner diameter of the nozzle was set at 1.5 mm, and the nozzle pressure was measured to be 0.2 MPa. What is the instantaneous flow rate through a single nozzle? ----The conveying medium is nitrogen. Request the calculation basis and results
As a supplementary point, the frictional pressure loss can be ignored.
