Calculate pipe diameter
Thread Content
I need to install a process pipeline now, with hydrogen and carbon monoxide as the media. The required outlet pressure is 30-40 KPA, and the gas flow rate is 3000-5000 NM3/h. Please help calculate what diameter of pipe is needed to meet these requirements.
First, without the temperature, it is impossible to calculate the actual volumetric flow rate. Secondly, the industry in which it is used, the composition of the medium, and especially the H2 content are also important, as this determines what standards should be applied. If the hydrogen content is high, the flow rate of hydrogen should be determined in accordance with the design specifications for hydrogen stations, generally not exceeding 15 m/s. Once you know the flow rate, even middle school students can calculate the pipe diameter. If there is a requirement for pressure drop, detailed calculations must be carried out using the formula; HG20570 can be used as a reference
The temperature is around 30 degrees, and the pressure drop is required to be reduced from 100 KPA to 30 KPA
